Adds a uclass to interface with a TEE (Trusted Execution Environment).
A TEE driver is a driver that interfaces with a trusted OS running in
some secure environment, for example, TrustZone on ARM cpus, or a
separate secure co-processor etc.
The TEE subsystem can serve a TEE driver for a Global Platform compliant
TEE, but it's not limited to only Global Platform TEEs.
The over all design is based on the TEE subsystem in the Linux kernel,
tailored for U-Boot.

rockchip: Fix rkimage format for SPL boot over USB
The 'rkimage' format used for booting rockchip boards over USB seems to
have been broken since commit 7bf274b9caab ("rockchip: mkimage: use
imagename to select spl hdr & spl size"). That commit adds an offset of
RK_SPL_HDR_START(=2048) to the location the 'RKxx' header is written
at. However the bootrom expects this header to be the first four bytes of
the image, not at offset 2048. This appears to have been a copy paste
error since the 'rksd' and 'rkspi' image types do require this offset.
Furthermore commit 111bcc4fb6cb ("rockchip: mkimage: pad the header to
8-bytes (using a 'nop') for RK3399"), commit 3d54eabcafec9 ("rockchip:
spl: RK3399: use boot0 hook to create space for SPL magic") and
commit 308277569229 ("rockchip: mkimage: update rkimage to support
pre-padded payloads") changed the way the space for the 'RKxx' header is
allocated and written to the image without adjusting 'rkimage'.
This commit fixes those mistakes and makes it possible to load u-boot SPL
over USB once more.

rockchip: rk3188: explicitly set vcc_sd0 pin to gpio on rk3188-radxarock
It is good practice to make the setting of gpio-pinctrls explicitly in the
devicetree, and in this case even necessary.
Rockchip boards start with iomux settings set to gpio for most pins and
while the linux pinctrl driver also implicitly sets the gpio function if
a pin is requested as gpio that is not necessarily true for other drivers.
The issue in question stems from uboot, where the sdmmc_pwr pin is set
to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage
loader. The regulator controlled by the pin is active-low though, so
when the dwmmc hw-block sets its enabled bit, it actually disables the
regulator. By changing the pin back to gpio we fix that behaviour.

The dwmmc controllers on rk3188 do not have idma support, so need to
use the fifo-mode and it my tests they became confused and stopped
working if the frequency was to high.
While I only tested in somewhat bigger steps, 32MHz for example
hung the controller, while reducing it to 16MHz worked just fine
and is reasonably fast to load a kernel from mmc.

mmc: dw_mmc: check fifo status with a timeout in fifo mode
While trying to enable the dw_mmc on rk3188 I managed to confuse
and hang the dw_mmc controller into not delivering further data.
The fifo state never became ready and the driver was iterating in
the while loop reading 0-byte packets forever.
So inspired by how other implementations handle this, check the fifo-
state beforhand and add a timeout to catch any glaring fifo issues
without hanging uboot altogether.

fs: btrfs: Fix cache alignment bugs
The btrfs implementation passes cache-unaligned buffers into the
block layer, which triggers cache alignment problems down in the
block device drivers. Align the buffers to prevent this.
