powerpc/mpc85xx: Add workaround for erratum A006379
Erratum A006379 says CPCHDBCR0 bit field [10:14] has incorrect default value after POR. The workaround is to set this field before enabling CPC to 0x1e. Erratum A006379 applies to T4240 rev 1.0 B4860 rev 1.0, 2.0 Signed-off-by: York Sun <yorksun@freescale.com>
