[Bhaumik Bhatt]

A set of patches for bug fixes and improved logging in mhi/core/boot.c.
Verified on x86 and arm64 platforms.

v6:
-Updated the MHI_RANDOM_U32_NONZERO to only give a random number upto the
supplied bitmask

v5:
-Updated the macro MHI_RANDOM_U32_NONZERO to take a bitmask as the input
parameter and output a non-zero value between 1 and U32_MAX

v4:
-Dropped the change: bus: mhi: core: WARN_ON for malformed vector table
-Updated bus: mhi: core: Read transfer length from an event properly to include
parse rsc events
-Use prandom_u32_max() instead of prandom_u32 to avoid if check in
bus: mhi: core: Ensure non-zero session or sequence ID values are used

v3:
-Fixed signed-off-by tags
-Add a refactor patch for MHI queue APIs
-Commit text fix in bus: mhi: core: Read transfer length from an event properly
-Fix channel ID range check for ctrl and data event rings processing

v2:
-Fix channel ID range check potential infinite loop
-Add appropriate signed-off-by tags
