This commit converts mccmon6's u-boot proper (in a single commit to avoid
build breaks) to use solely DM/DTS.

The DTS description of the mccmon6 has been ported from Linux kernel
(v4.20, SHA1: 8fe28cb58bcb235034b64cbbb7550a8a43fd88be)

Without this we miss almost the half of output (U-boot version,

According to IMX28CEC rev. 4, 10/2018, Table 15. Recommended Operating
Conditions, page 16, the VDDD should be set to 1.55V when the CPU is
operating at 454MHz. This is the case in U-Boot, hence increase the
VDDD voltage. This fixes instability when performing TFTP transfers.
Increase the brownout threshold to 1.4V. The documentation recommends
1.45V setting for the brownout, however, this triggers failure during
power block init, so keep the brownout slightly lower.

imx6_is_bmode_from_gpr9 always returns false, because
IMX6_SRC_GPR10_BMODE is 1<<28 and gets casted to u8 on return.

This moves the function body into imx6_src_get_boot_mode, since that is the
only one using it and it is on the same abstraction level (accessing
registers directly).

At present some boards generate kwbimage.cfg in the source tree
during the build. This breaks buildman testing on some systems
where the source tree is read-only. Update makefile rules to
generate it in the build tree instead.

Note some other boards have the kwbimage.cfg file written in
advance, hence we need check if the file exists in the build
tree first, otherwise we fall back to one in the source tree.

U-Boot cleans and invalidate L1 and L2 caches before jumping to Linux
by set/way in cleanup_before_linux(). Additionally there is a custom
hook provided to clean and invalidate L3 cache.

Unfortunately on K3 devices(having a coherent architecture), there is no
easy way to quickly clean all the cache lines for L3. The entire address
range needs to be cleaned and invalidated by Virtual Address. This can
be implemented using the L3 custom hook but it take lot of time to clean
the entire address range. In the interest of boot time this might not be
a viable solution.

The best hit is to make sure the loaded Linux image is flushed so that
the entire image is written to DDR from L3. When Linux starts running with
caches disabled the full image is available from DDR.
