A set of patches for bug fixes and improved logging in mhi/core/boot.c.

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

v5:

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

v3:
-Fixed signed-off-by tags
