habanalabs/gaudi: use 8KB aligned address for TPC kernels
I$ prefetch is enabled when sending a TPC kernel to initialize the TPC
memory, and it has a restriction that the base address will be aligned
to 8KB.
Currently the base address is 128 bytes from the start address of the
device SRAM, so prefetching will start 128 bytes before the actual
kernel memory.
Modify the kernel address to be 8KB aligned.

habanalabs: remove some f/w descriptor validations
To be forward-backward compatible with the firmware in the initial
communication during preboot, we need to remove the validation of the
header size. This will allow us to add more fields to the
lkd_fw_comms_desc structure.
Instead of the validation of the header size, we just print warning
when some mismatch in descriptor has been revealed, and we calculate
the CRC base on descriptor size reported by the firmware instead of
calculating it ourselves.
Newer ASICs code changes more often, has more chance to fail
compilation. So, let's compile them first so errors in those files
will fail compilation sooner.

habanalabs/gaudi2: increase hard-reset sleep time to 2 sec
The access to the device registers is blocked during hard reset, until
preboot runs and allows the access to specific registers, including the
PSOC BTM_FSM register which is used to know when the reset is done.
Between the reset request and until this register is polled there is a
small delay of 500 msec which is not enough for F/W to process the reset
and for preboot to run, so the register might be accessed while it is
blocked.
To avoid it, increase the delay to 2 sec.
The code used the mmu mutex to protect access to the context's page
tables and invalidation of the MMU cache. Because pgt are per
context, the mmu mutex was a member of the context object.
The problem is that the device has a single MMU invalidation h/w
(per MMU). Therefore, the mmu mutex should not be a property of the
context but a property of the device.

habanalabs/gaudi2: mark PCIE access error as fatal
F/W events are enabled in a late phase of the device init, so an event
for a PCIE access error during the init, can be received after the init
is already done and considered as successful.
A resulting device reset, which does the same H/W init, can end
similarly with this event right after the reset is done and considered
as successful, and a loop of this sequence can continue.
To avoid it mark the PCIE access error as a fatal event, so after 2
consecutive events no more resets will be done.
Currently, to get engines status, user needed to read debugfs file
with root permissions.
This new uapi allows user apace apps retrieve status, so for example,
in case of failure, status can be retrieved immediately by the
application itself which runs without root permissions.
The macro argument <val> is cast-ed to u32 in some of the places.
Because this arg can be some arithmetic computation (e.g. address +
offset) the cast should be on the whole expression.
habanalabs/gaudi: increase default cs timeout to 10 minutes
In order to improve scalability and reduce host overhead, it is better
to increase the default TDR timeout of Gaudi1 from 30 seconds to
10 minutes.
This will allow the DL Framework (e.g. PyTorch, TensorFlow) to remove
the host sync they are using now and improve overall performance on
scaleout training.
Note that one can always set the timeout to a custom value via
a kernel module parameter given during driver load.
habanalabs: add return code field to module iterator
Up until now the module iterator called void callback functions
and so caller activating callback that may fail suffered from 2 issues:
1. The need to "plant" return called in the private data. This is a
drawback since the iterator itself should not be aware of the private
data of the caller.
2. Due to 1 even in a failure the iterator would keep iterating instead
of break upon error.
To overcome this an optional rc field added to the iterator context.
habanalabs/gaudi2: enable all MMU SPI/SEI interrupts
Currently only part of the MMU SPI/SEI interrupts are enabled, although
there is no real reason to not enable all.
The only exception is "burst_fifo_full" which is expected for PMMU
because it has a 2 entries FIFO, and thus is it not enabled for it.
Follow the advice of the Documentation/filesystems/sysfs.rst
and show() should only use sysfs_emit() or sysfs_emit_at()
