target/alpha, hppa: Remove unused parent_reset fields

The Alpha and HPPA CPU class structs include a 'parent_reset'
field which is never used; delete them.

(These targets don't seem to implement reset at all; if they did they
should do it using the three-phase reset mechanism, which uses a
'ResettablePhases parent_phases' field instead of the old
'DeviceReset parent_reset' field.)
