Follow the lead of the TI kernels by removing PRCM #2 and adding PRCM
#3 and #4 to the rate-table entries. According to TI, having #2 and
#3 together is known to be a bad combination.
Also, change the default divider values for the PRCM #5a setting to
match those of the TI kernel, which use 264MHz intstead of 266.
