wifi: ath11k: fix wrong definition of CE ring's base address

Base address of CE ring is defined as u32, currently this works
because coherent DMA mask configured as 32 bit:

	#define ATH11K_PCI_COHERENT_DMA_MASK	32

However this mask could be changed once firmware bugs are fixed
to fully support 36 bit DMA addressing. So to protect against any
future changes to the DMA mask, change the type of the fields that
are dependent upon it.

This is found during code review. Compile tested only.
