93ab6ca1c8 powerpc/p2041rdb: remove watch dog related codes
CPLD 2.2 removed board watch dog support due to the limitation of CPLD
capacity after adding all the requested features, such as switch overriding.
There is no pin-compatible upgrade part available for current PCB design.
So remove codes related to it.

ba50fee6ae powerpc/p2041rdb: update cpld reset command according to CPLD 2.0
CPLD 2.0 provides a new register which bit[0] is set to '1' will reset
board with initializing the CPLD registers to default values. And add
bit[6] of register at offset 0x5 to use to enable flash bank selection.
