Use array finders for HD6301 keyboard and joystick ports. Swap players for joystick and button inputs (needed for mouse to work). Remove shifter mode 1 kludge that seems to hurt more than help [AJR].

- osborne1.cpp: Revert floppy device back to SSDD. Partially reverts an old commit from @Robbbert (https://github.com/mamedev/mame/commit/247939853301565efd348cad12b04fc957707bc2) where the floppy device was (mistakenly?) set to FLOPPY_525_QD (quad density) from FLOPPY_525_SSDD (single-sided double-density). As far as I am aware, the Osborne1 only supported SSSD and SSDD disks. Revert appears to resolve known Osborne1 issues [theoldsport].
