U-Boot mostly uses hex for value input, largely because addresses are much
easier to understand in hex.
But in some cases a decimal value is requested, such as where the value is
small or hex does not make sense in the context. In these cases it is
sometimes useful to be able to provide a hex value in any case, if only to
resolve any ambiguity.
Add this functionality, for increased flexibility.

If we see 0x then we can assume this is the start of a hex value. It
does not seem necessary to check for a hex digit after that since it will
happen when parsing the value anyway.

cases for when a 0x prefix is used.

There are several outstanding issues as to why this does not apply
to FSP1:
* For FSP1, the system memory and reserved memory used by FSP are
already programmed in the MTRR by FSP.
* The 'mtrr_top' mistakenly includes TSEG memory range that has the
same RES_MEM_RESERVED resource type. Its address is programmed
and reported by FSP to be near the top of 4 GiB space, which is
not what we want for SDRAM.
* The call to mtrr_add_request() is not guaranteed to have its size
to be exactly the power of 2. This causes reserved bits of the
IA32_MTRR_PHYSMASK register to be written which generates #GP.
For FSP2, it seems this is necessary as without this, U-Boot boot
process on Chromebook Coral goes very slowly.

Current mtrr_commit() logic assumes that MTRR MSRs are programmed
consecutively from index 0 to its maximum number, and whenever it
detects an unused one, it clears all other MTRRs starting from that
one. However this may not always be the case.
In fact, the clear is not much helpful because these MTRRs come out
of reset as disabled already. Drop the clear codes.

If for some reason, TSC timer frequency cannot be determined from
hardware, nor is it specified in the device tree, U-Boot will panic

The U-Boot port for ST-Ericsson Ux500 is currently only used on the
"stemmy" board, where U-Boot runs after firmware that already sets up
a boot splash screen. This means that the display is already on
and we can just continue using it for U-Boot.
Add a simple driver that simplifies this by reading the display
configuration (e.g. screen size, bpp) from the hardware registers.
It also checks the configured "source synchronization" - for some
displays (usually DSI command mode displays) we need to explicitly
trigger a software sync. This is done through the video_sync()
callback that triggers the sync and wait for completion.

The autoboot tests are a recent addition to U-Boot, providing much-needed
coverage in this area.
A side effect of the keyed autoboot test is that this feature is enabled
in sandbox always. This changes the autoboot prompt and confuses the
pytests. Some tests become slower, for example the vboot tests take about
27s now instead of 3s.
We don't actually need this feature enabled to be able to run the tests.
