ARM: OMAP: fix default sys_ck.rate for boot-time DPLL detection
In the clock init code, the DPLL value set by the bootloader is
queried, but always turns zero due it's parent clock (sys_ck) having
no default rate. This results in the improper setting of the default
PRCM rate-table entry and any queries of virt_prcm_set rate to return 0.
Rather than setting a static sys_ck.rate, detect the correct value at
boot time.
