selftests/bpf: Add tests for target information in bpf_link info queries

Extend the fexit_bpf2bpf test to check that the info for the bpf_link
returned by the kernel matches the expected values.

While we're updating the test, change existing uses of CHEC() to use the
much easier to read ASSERT_*() macros.

v2:
- Convert last CHECK() call and get rid of 'duration' var
- Split ASSERT_OK_PTR() checks to two separate if statements

mailbox: sprd: Add supplementary inbox support

Some sensors connected to Unisoc mailbox will send data very frequently.
This makes channel 0 very busy and the messages from other remote cores
not able to be handled as soon as possible.

It's a trick (un-documented) from Unisoc ASIC designers to resolve this
special requirement that an inbox assigned to one of the remote cores
before was modified to be exposed to host cpu core.

Then from host side, a supplementary inbox is added for transferring mass
but not emergency messages from the remote cores, such as step counting
sensor, with an independent FIFO and interrupt which is as same as channel
0. Meanwihle, inbox part of this channel is still kept for original remote
core to use.

mailbox: sprd: Introduce refcnt when clients requests/free channels

Unisoc mailbox has no way to be enabled/disabled for any single channel.
They can only be set to startup or shutdown as a whole device at same time.

Add a variable to count references to avoid mailbox FIFO being reset
unexpectedly when clients are requesting or freeing channels.

Also add a lock to dismiss possible conflicts from register r/w in
different startup or shutdown threads. And fix the crash problem when early
interrupts come from channel which has not been requested by client yet.
