drm/xe: Add functions to convert regular address to canonical address and back
Some instructions requires canonical address like
MI_BATCH_BUFFER_START(UMDs must call xe_exec with a canonical address
for Xe2+).
So here adding functions to convert regular address to canonical
address and back, the first user of this functions will be added
in the next patch.
v3:
- inline removed
- rename highest_address_bit_get() to ppgtt_msb_get()
v4:
- use xe->info.va_bits instead of xe->info.dma_mask_size
