iwm: Increate the flux write buffer size for better performance (complete sector write in a single call)
2gs: Correct the q3 clock value, making (sync) writes reliable
z80scc: Removed unused Z80SCC_USE_LOCAL_BRG and simplified
WR15_ZEROCOUNT usage to reduce the likelihood of needless timer
activation.
mips3drc: Additional micro-optimizations to generate_checksum_block.
Partially reverts an old commit from @Robbbert (2479398533) 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 [5792](https://mametesters.org/view.php?id=5792) (thanks to @Osso13 for pointing this out) and [8100](https://mametesters.org/view.php?id=8100) @cuavas.
