[U-Boot] [v2][PATCH] Added P1020 Processor Support.

[Poonam Aggrwal]

P1020 is another member of QorIQ series of processors which falls in ULE
category. It is an e500 based dual core SOC.
Being a scaled down version of P2020 it has following differences from P2020:
- 533MHz - 800MHz core frequency.
- 256Kbyte L2 cache
- Ethernet controllers with classification capabilities.
Also the SOC is pin compatible with P2020
