(for MB-6892). For now these behave the same as bml3 (MB-6890).
Refactor disk controllers and kanji ROM as slot devices. This allows
switching between MP-1802 and MP-1805 disk controllers. MP-1805 disk
controller now works. Kanji ROM now works.
Keyboard scanning in 'counter disabled' mode now works.
imgtool: Add bml3 driver, supporting both single-density (MP-1805
controller) and double-density (MP-1802 controller) disks in D88 format.
mc6843: Work around floppy_get_device() not finding drives attached to a
slot device.Store all 8 bits in CTAR current track register, rather than
excluding bit 7 (needed for bml3 MP-1805 boot)

Remaining TODO list:
- take WP into account
- test the amstrad, implement its observational format (edsk) using
pasti as a start. Or find the legendary amstrad IPFs. Or both.
- correct read track, the implementation is completely wrong. See
previous for testing, it's only used in protections the check the
inter-sector gaps.
- shake and bake on the amstrad, protections are the best to find bugs
in a fdc
- add the scan id commands, but nothing seems to use them
- debug the 2.88M formatting which is unreliable. Fix its IDAM/DAM
gap size on formatting too (but that's not what's making it
unreliable)
- test all the systems that were hit, and fix what needs to be fixed.
Beware that multiple problems may happen:
- upd765 may be wrong
- the driver may not be working
- the hookup may be wrong/incomplete (bitrate selection and floppy
rpm in particular)
- the driver may be too limited for the new implementation (the x68k
dma device does not handle non-instant dma yet for instance)
- report invalid command when appropriate depending on the actual chip
emulated
- add the russian clones with their real names

note: hoarded dump removed too from coco_cart.xml, this will not be tolerated
