ARM: uniphier: collect clock/PLL init code into a single directory
Now PLLs for DRAM controller are initialized in SPL, and the others

sunxi: musb: Re-init musb controller on repeated probe calls
With sunxi-musb musb_lowlevel_init() can fail when a charger; or no cable
is plugged into the otg port.
To avoid leaking the struct musb allocated by musb_init_controller()
on repeated musb_usb_probe() calls, we were caching its result.
But musb_init_controller() does more, such as calling sunxi_musb_init()
which enables the clocks.
Not calling sunxi_musb_init() causes the musb controller to stop working
after a "usb reset" since that calls musb_usb_remove() which disables the
clocks.
This commit fixes this by removing the caching of the struct returned
from musb_init_controller(), it replaces this by free-ing the allocated
memory in musb_usb_remove() and calling musb_usb_remove() on
musb_usb_probe() errors to ensure proper cleanup.
While at it also make musb_usb_probe() and musb_usb_remove() static.
