Pali Rohár 1f90be6f34 board: freescale: p1_p2_rdb_pc: Add workaround for board reset reboot loop 
CPLD's system reset register on P1/P2 RDB boards is not autocleared after
flipping it. If this register is set to one in 100ms after reset starts
then CPLD triggers another CPU reset.

This means that trying to reset board via CPLD system reset register cause
reboot loop. To prevent this reboot loop, the only workaround is to try to
clear CPLD's system reset register as early as possible. U-Boot is already
doing it in its board_early_init_f() function, which seems to be enough as
register is cleared prior CPLD triggers another reset.

But board_early_init_f() is not called from SPL and therefore usage of SPL
can cause reboot loop.

To prevent reboot loop when using SPL, call board_early_init_f() function
in SPL too. For accessing CPLD memory space it is needed to have CPLD entry
in TLB.

With this change it is possible to trigger board reset via CPLD's system
reset register on P2020 RDB board.
