Merge bug fixes from upstream

[gameblabla]

I've noticed that there are still a couple of fixes that are not fixed.
There's the Driver fix that should be done (see your PRs) but also :

• Fixed bug where MSB of a 15-bit BGR color could corrupt green value.
  Fixed bug where MSB of a 15-bit BGR color could corrupt green value. notaz/pcsx_rearmed#160

This affects the NEON backend, which includes the Funkey version

• cdrom: add missing BCD->int convert in cdrFreeze()
  cdrom: add missing BCD->int convert in cdrFreeze() notaz/pcsx_rearmed#147

This affects some EBP eboot images.

• Gte_divider from MAME
  Replace existing gte_divider with MAME's version notaz/pcsx_rearmed#156

• HLE save fix
  Fix corrupted memory card saves when using HLE notaz/pcsx_rearmed#139

This fixes an oversight in my initial HLE patch. (i think you merged it tho)

Here are my own patches (some of which got merged)

• CHD support (merged)
  CHD support from libretro's fork. notaz/pcsx_rearmed#188

Could actually be useful for slow storage like on the Funkey-S. (there is an async patch to address that however)

• gte: Fix gteH division and sign extension (merged)
  gte: Fix gteH division and sign extension (from PCSX4ALL/senquack) notaz/pcsx_rearmed#185

• Fixed Linked List DMA end marker. (merged)
  Fixed Linked List DMA end marker. notaz/pcsx_rearmed#183

• CDRom timings changes
  CDRom timings changes notaz/pcsx_rearmed#184

This fixes the freeze after the Lunar Cry FMV in FF8, the de-synchronization in CTR's intro, Zeus fight in Xenogears and possibly other games as well. (Author said they are most likely wrong but it's better than it was before so far)

There are more that are unmerged of course but that's most of it.
