Subject: [PATCH] ARM: OMAP: timer32K: fix all kernel-doc warnings

Fix kernel-doc warnings reported by the kernel test robot:

timer32k.c:186: warning: cannot understand function prototype: 'struct timespec64 persistent_ts; '
timer32k.c:191: warning: Function parameter or member 'ts' not described in 'omap_read_persistent_clock64'
timer32k.c:216: warning: Function parameter or member 'vbase' not described in 'omap_init_clocksource_32k'
timer32k.c:216: warning: Excess function parameter 'pbase' description in 'omap_init_clocksource_32k'
timer32k.c:216: warning: Excess function parameter 'size' description in 'omap_init_clocksource_32k'
timer32k.c:216: warning: No description found for return value of 'omap_init_clocksource_32k'

Fixes: a451570c008b ("ARM: OMAP: 32k counter: Provide y2038-safe omap_read_persistent_clock() replacement")
Fixes: 1fe97c8f6a1d ("ARM: OMAP: Make OMAP clocksource source selection using kernel param")
