powerpc, 8xx: Simplify brgclk calculation and remove get_brgclk()
divider is calculated based on SCCR_DFBRG, with:
SCCR_DFBRG 00 => divider 1 = 1 << 0
SCCR_DFBRG 01 => divider 4 = 1 << 2
SCCR_DFBRG 10 => divider 16 = 1 << 4
SCCR_DFBRG 11 => divider 64 = 1 << 6
This can be easily converted to a single shift operation:
divider = 1 << (SCCR_DFBRG * 2)
