In order to have a proper runtime-modifyable page table API (e.g. to
remap DRAM after it was intialized), we need to remove any external
bookkeeping kept in global variables (which do not persist across
stages) from the MMU code. This patch implements this in a similar way
as it has recently been done for ARM32 (marking free table slots with a
special sentinel value in the first PTE that cannot occur as part of a
normal page table).
Since this requires the page table buffer to be known at compile-time,
we have to remove the option of passing it to mmu_init() at runtime
(which I already kinda deprecated before). The existing Tegra chipsets
that still used it are switched to instead define it in memlayout in a
minimally invasive change. This might not be the best way to design this
overall (I think we should probably just throw the tables into SRAM like
on all other platforms), but I don't have a Tegra system to test so I'd
rather keep this change low impact and leave the major redesign for
later.
Also inlined some single-use one-liner functions in mmu.c that I felt
confused things more than they cleared up, and fixed an (apparently
harmless?) issue with forgetting to mask out the XN page attribute bit
when casting a table descriptor to a pointer.

Among its other restrictions (which are noted in a comment above the
function prototype and stay in place), our makeshift fine-grained page
table support for ARM32 has the undocumented feature that it relies on
a global bookkeeping variable, causing all sorts of fun surprises when
you try to use it from multiple stages during the same boot. This patch
redesigns the bookkeeping to stay completely inline in the (persistent)
TTB which should resolve the issue. (This had not been a problem on any
of our platforms for now... I just noticed this because I was trying to
solve the same issue on ARM64.)

Upon bootup the hardware reads at minimum 256 * 16 bytes (4Kb, or 32KB) over
I2C on a system with all DIMM slots populated. If even one of those reads
has a single flipped bit in it (due to EMI, cross coupling with another trace,
or just poor margins on some cheap DIMM) the system will hang and require a
hard reset. In practice I've seen failure rates as high as 1 failed boot in
50 due to this issue, granted with cheap DIMMs, but even so retrying the read
resolves the corruption issue.
I2C is not designed for continuous data transmission with high reliability, and
there is no hardware error checking, therefore a single retry when transferring
this amount of data makes sense.
