powerpc: Add cpu_secondary_init_r to allow for initialization post env setup
We can simplify some cpu/SoC level initialization by moving it to be
after the environment and non-volatile storage is setup as there might
be dependancies on such things in various boot configurations.
For example for FSL SoC's with QE if we boot from NAND we need it setup
to extra the ucode image to initialize the QE. If we always do this
after environment & non-volatile storage is working we can have the code
be the same regardless of NOR, NAND, SPI, MMC boot.

The ngPIXIS is an FPGA used on the reference boards of most Freescale PowerPC
SOCs. Although programming the ngPIXIS is mostly standard on all boards that
have it, the P1022DS is unique in that the ngPIXIS needs to be programmed in
"indirect" mode whenever the video display (DIU) is active.
To support indirect mode, and to make it easier to support other quirks on
future reference boards, the low-level ngPIXIS functions are all marked as
weak, so that board-specific code can override any of them. We take advantage
of this feature on the P1022DS, so that we can properly reset the board when
the DIU is active.
