V5:
- Removed mhi_uci_drv structure.
- Used idr instead of creating global list of uci devices.
- Used kref instead of local ref counting for uci device and
open count.
- Removed unlikely macro.
V4:
- Fix locking to protect proper struct members.
- Updated documentation describing uci client driver use cases.
- Fixed uci ref counting in mhi_uci_open for error case.
- Addressed style related review comments.
V3: Added documentation for MHI UCI driver.
V2: Added mutex lock to prevent multiple readers to access same
mhi buffer which can result into use after free.
