Qualcomm clock fixes for v7.1

Browse Source 
The parking of shared RCGs during registration parks the MDP source
 clock, disabling display until the msm display driver successfully
 initializes the hardware again. Mark this clock on Makena and Hamoa as
 "no_init_park" to retain a working recovery console etc.
