openfirmware: adjust for 64bit

Sparcv9 runs Openboot in 64 bit mode, which means the cell size is
64bit. Use intptr_t where appropriate to make the open firmware calls
work.

Beware, some values are still 32bit, this matters for example for
of_getprop, if you get 32bits into a 64bit variables it will be in the
MSB of it (big endian only weakness...) and confuse things. See for
example in console.cpp, where the input and output handles are retrieved
as 32bit values. It seems wise to check the expected size when using
of_getprop in these cases, instead of just checking for errors.

OpenFirmware: Make of_milliseconds() return error

The only user of of_milliseconds(), the boot loader's system_time(),
checks for an error that would never be signalled since the zero-initialized
number of milliseconds would always be returned.

Return OF_FAILED instead to allow explicit error handling in that case.

While this is a behavioral change, it is not yet a functional change,
for system_time()'s implementation translates OF_FAILED back to zero currently.

Resolves part of ticket #6061.
