From: Joonyoung Shim <jy0922.shim@xxxxxxxxxxx>
This patch adds the CLK_SET_RATE_PARENT flag for 'aclk_g3d' clock and parent
clocks becuase 'aclk_g3d' is used to change GPU frequency for DVFS (Dynamic
Voltage Frequency Scaling) feature and adds CLK_IGNORE_UNUSED flags to
'aclk_asyncapbs_g3d'/'aclk_asyncapbm_g3d' clocks to access the SFR
(Special Funciton Regiser) of MALI device.
