Like other Allwinner A64 boards, pinebook also need altering
auto-numbering of mmc2 to mmc1 which is available in common
sunxi dsti file, sunxi-u-boot.dtsi
Pinebook has a separate sun50i-a64-pinebook-u-boot.dtsi which
takes more precedence for u-boot.dtsi inclusion and it eventually
failed to include the sunxi-u-boot.dtsi.
So, this patch add support to include the sunxi-u-boot.dtsi in the

Environment and fastboot mmc devices are configured based on the number
of mmc slots defined on particular board configs, MMC_SUNXI_SLOT_EXTRA.
If MMC_SUNXI_SLOT_EXTRA is more than 1, the default env and fastboot
mmc devices is mmc1 by assuming mmc0 is SD and mmc1 is emmc device.
But with DM_MMC the mmc devices are numbered as per the dts node
enablement. If there is a chance of having enabling all mmc nodes
in dts say mmc0, mmc1, mmc2 then the default env and fastboot devices
will failed to assign proper emmc device since mmc2 is emmc in most
of the Allwinner platforms.
So, we need to alter the auto-numbering by aliasing mmc2 to mmc1 since
aliases take precedence over auto-numbering.
If the dts enables mmc0, mmc1, mmc2, then all the nodes will probe
sequentially and auto-numbered as it is. but when aliases mmc1 with mmc2
the resulting number should be that mmc0 is till mmc0, mmc2 become mmc1
and mmc2 become mmc1
Without aliases of mmc1 = &mmc2;
-------------------------------
MMC: mmc@1c0f000: 0, mmc@1c10000: 1, mmc@1c11000: 2
With aliases of mmc1 = &mmc2;
----------------------------
MMC: Device 'mmc@1c11000': seq 1 is in use by 'mmc@1c10000'
mmc@1c0f000: 0, mmc@1c10000: 2, mmc@1c11000: 1
Loading Environment from FAT... OK
Some platforms like A20 has mmc0...mmc3, but there is no usecases now
for enabling all mmc controllers in any of A20 board dts files.

Some Allwinner clock devices have parent clocks and reset gates itself,
which need to be activated for them to work.
Add some code to just assert all resets and enable all clocks given.
This should enable the A80 MMC config clock, which requires both to be
activated. The full CCU devices typically don't require resets, and have
just fixed clocks as their parents. Since we treat both as optional and
enabling fixed clocks is a NOP, this works for all cases, without the need
to differentiate between those clock types.

If a board DT describes a cd-gpios property, but also marks the storage
as non-removable, we must ignore the GPIO (as Linux does).

Enabling DM_MMC skips the call to mmc_pinmux_setup() in board.c, as this
is supposed to be handled by the MMC driver, using DT information.
However we don't have a pinctrl driver yet, but would still like to keep
the working pinmux setup for our MMC devices. So bring this particular
call back to the DM_MMC code flow.
When booting from either SD card or eMMC, the SPL does the setup for us,
but when booting from SPI or USB we must not skip this part.
Fixes, boot via FEL or SPI flash, where the SPL won't setup the pinmux

At default, u-boot reserves the memory from SP - 4KB to DRAM end for
lmb in arch_lmb_reserve. So lmb won't allocate any memory from it.
But we found the 4K gap for SP is not enough now, because some FDT
updating operations are added in our u-boot before jumping to kernel,
which needs larger stack. This causes the lmb allocated memory is overwritten
by stack.
Fix the issue by implementing the board_lmb_reserve to reserve from
SP - 16KB to memory end for lmb.
