powerpc/p4080: Add support for secure boot flow
Pre u-boot Flow:
1. User loads the u-boot image in flash
2. PBL/Configuration word is used to create LAW for Flash at 0xc0000000
(Please note that ISBC expects all these addresses, images to be
validated, entry point etc within 0 - 3.5G range)
3. ISBC validates the u-boot image, and passes control to u-boot
at 0xcffffffc.
Changes in u-boot:
1. Temporarily map CONFIG_SYS_MONITOR_BASE to the 1M
CONFIG_SYS_PBI_FLASH_WINDOW in AS=1.
(The CONFIG_SYS_PBI_FLASH_WINDOW is the address map for the flash
created by PBL/configuration word within 0 - 3.5G memory range. The
u-boot image at this address has been validated by ISBC code)
2. Remove TLB entries for 0 - 3.5G created by ISBC code
3. Remove the LAW entry for the CONFIG_SYS_PBI_FLASH_WINDOW created by
PBL/configuration word after switch to AS = 1
