[PATCH v2 7/8] Add debug log info to vfe block init and set clock rate

[George Chan via B4 Relay <devnull+gchan9527.gmail.com@kernel.org>]

From: George Chan <gchan9527@gmail.com>

Print out missing clock's name when doing msm_vfe_subdev_init().
Also print out min clock rate required at vfe_set_clock_rates().
