[PATCH] drm/panthor: fix kernel-doc for nested struct members

[Rosen Penev <rosenp@gmail.com>]

The kernel-doc comments for members of nested structs in panthor use
the bare member names, which kernel-doc reports as excess members of
the outer struct, for example:

  panthor_fw.c:143 Excess struct member 'start' description in 'panthor_fw_binary_section_entry_hdr' (did you mean one of: 'va.start', 'data.start')
  panthor_device.h:338 Excess struct member 'core' description in 'panthor_device' (did you mean one of: 'clks.core', 'clks.coregroup', 'coherent')

Prefix the member names with the enclosing member, as kernel-doc
suggests, in panthor_fw.c and panthor_device.h. In panthor_gem.h, the
label lock is documented as @lock.str instead of @label.lock; fix that
too. While at it, fix a typo in the @data.buf description.
