plat: marvell: ap807: implement workaround for errata-id 3033912

ERRATA ID: RES-3033912 - Internal Address Space Init state causes
a hang upon accesses to [0xf070_0000, 0xf07f_ffff]
Workaround: Boot Firmware (ATF) should configure CCU_RGF_WIN(4) to
split [0x6e_0000, 0xff_ffff] to values [0x6e_0000, 0x6f_ffff] and
[0x80_0000, 0xff_ffff] that cause accesses to the segment of
[0xf070_0000, 0xf07f_ffff] to act as RAZWI. Reuse common
work-around code for both AP806 and AP807.
