Hello,
This is a v2 of the belated follow-up from a few of my earlier attempts to fix

We had completely run out of TBFLAG bits.
Split A- and M-profile bits into two overlapping buckets.
This results in 4 free bits.

This is part of a reorganization to the set of mmu_idx.
The Secure regimes all have a single stage translation;
there is no point in pointing out that the idx is for stage1.

This is part of a reorganization to the set of mmu_idx.
The EL1&0 regime is the only one that uses 2-stage translation.
Spelling out Stage avoids confusion with Secure.

This inline function has one user in cpu.c, and need not be exposed
otherwise. Code movement only, with fixups for checkpatch.

Prepare for, but do not yet implement, the EL2&0 regime.
This involves adding the new MMUIdx enumerators and adjusting
some of the MMUIdx related predicates to match.

The corner-case codepath was adjusting nexttick such that overflow
wouldn't occur when timer_mod() scaled the value back up. Remove a use
of GTIMER_SCALE and avoid unnecessary operations by calling
timer_mod_ns() directly.

Public bug reported:
So I have installed FreeDOS on my USB thumbdrive, by using Rufus.
Everything goes as expected so far. That's good.
When I run QEMU with this command line:
qemu-system-x86_64.exe -drive file=\\.\PhysicalDrive1
it of course is read-only, just like the resulting console
