ENGR00223797-10 ARM:MX6 Kconfig:Support MX6_CLK_FOR_BOOTUI_TRANS

This patch adds CONFIG_MX6_CLK_FOR_BOOTUI_TRANS support. Setting
this Kconfig may keep enable IPU related clocks and PWM clocks
and avoid setting IPU related clocks' parents when initializing
clock tree so that bootloader splashimage can transition to
kernel smoothly.
