amd/common/block/gpio/gpio: don't use -1 as bitmask in gpio_or32
The and-mask passed to the gpio_update32 call needs all 32 bits to be
set to ones. When building as 32 bit binary the -1UL will result in the
needed bit mask, but for a 64 bit build the constant would have 64 bits
set to ones which then gets truncated to 32 bits causing a compiler
error. Use 0xffffffff as bit mask instead which behaves correctly in
both cases and also clarifies what this is doing.
TEST=Timeless build for Chausie results in identical image.
