[PATCH v4 0/2] bus: mhi: Fix MHI on big endian architectures

[Paul Davey <paul.davey@alliedtelesis.co.nz>]

I encountered some problems getting the MHI driver to work on an Octeon
3 platform these seem to all be related to endianness issues.  The modem
interface appears to require the DMA structures to be in little endian,
however the MHI core driver was assembling them in native endianness.

Using little endian explicitly allows the interface to function as
expected.

Changes in v4:
  - add Fixes and Reviewed-By tags as requested/offered.
Changes in v3:
  - removed change of doorbell helper functions db_val type from
    dma_addr_t to __le64 favouring doing conversion only when writing to
    context wp fields.  
Changes in v2:
  - use __fls instead of find_last_bit in pm_state conversion patch as
    requested by Hemant Kumar <hemantk@codeaurora.org>
