clk: qcom: sa8775p: Fix USB clock configuration and add resets

Browse Source 
Correct USB30 primary clock RCG configuration and add missing
USB3_PRIM_PHY_AUX_CMD_RCGR RCG configuration.
Above taken from Linux commit 08c51ceb12f7 ("clk: qcom: add the GCC driver for sa8775p")

Add missing USB3_PRIM_PHY_PIPE_CLK gate clock definition.
Extend reset map with USB-related BCR entries and video BCR
for comprehensive reset control support.
