mb/google/guybrush/var/baseboard: Set Clk request for WLAN/SD/WWAN/SSD device
Setting the clock source depends on clock request pin for WLAN/SD/SSD device. Also turn off the unused (4/5/6) clock sources. In guybrush, clock source 0/1/2/3 are routed for WLAN/SD/WWAN/SSD device.
BUG=b:186384256 BRANCH=none TEST=Verify the config setting can update to the GPPCLKCONTROL registers.
