m68k: make HPDCA and HPAPCI bools

The only user -- 8250_hp300 -- tests for CONFIG_HPDCA and CONFIG_HPAPCI.
It does not test for *_MODULE variants. That means that if someone sets
the configs to =m, the code is not compiled at all.

There is actually no point having these as tristate. Switch them to
bool.
