MPC8379E RM says (10-34): Once LCRR[CLKDIV] is written, the register should be read, and then an isync should be executed. So update this in code. Also define a LCRR mask for processors, which uses not all bits in the LCRR register (as for example mpc832x did).

changes since v1:
- added comment from DaveLiu. moved LCRR setting to cpu_init_r()
changes since v2:
- added comment from Kim Phillips changed LCRR_MASK to 0x7fffffff use clrsetbits()
Heiko - let's go with the SCCR approach of setting bits in the LCRR, and have board config files only specify values for fields they're modifying from the reset value for their processor (this can be extended to 85xx-world).
