Fix the boot regression by adding the LPUART IPG entries.

U-Boot SPL loads the device-tree directly behind main U-Boot overlapping
the .bss section. reserve_fdt() is called in board_init_f() to relocate the
device-tree to a safe location.
Debug UARTs are enabled before board_init_f(). With sbi_dbcn_available in
the .bss section the device-tree is corrupted when _debug_uart_init() is
called in the SBI serial driver. Move the variable to the .data section.

Two patches make sure our DRAM init does not actually change the content
of the DRAM array, which allows to use DRAM for Linux' pstore

We get SPI support for U-Boot proper for one more SoC, that patch was

As an added bonus, we get the defconfig file for a new board, the DT was
already synced from the kernel tree.

These SoCs have two SPI controllers that are quite similar to the SPI
on previous Allwinner SoCs. The main difference is that new SoCs
don't have a clock divider (SPI_CCR register) inside SPI IP.
Instead SPI sample mode should be configured depending on the input clock.
For now SPI input clock source selection is not supported by this driver,
and only HOSC@24MHz can be used as input clock. Therefore, according to
the, manual we could change the SPI sample mode from delay half
cycle(default) to normal.
This patch adds a quirk for this kind of SPI controllers

This driver supports the I2C module on the Renesas RZ/G2L (R9A07G044)
SoC, also known as the RIIC module.
This patch is based on both the u-boot driver in the Renesas RZ BSP
3.0.5 release [1] (commit 7fcc1fdc2534), and the Linux v6.7 driver
(commit 0dd3ee311255).
Support for deblocking the I2C bus is included as this may be needed
after triggering a reset via the Power Management IC (PMIC) over I2C
(the PMIC asserts the reset line before the SoC completes the I2C write
transaction with obvious bus locking effects). If the SDA line is
observed to be low during initialisation, we automatically attempt to
deblock.

When enabling/disabling a clock or reset signal, confirm that the change
has completed before returning from the function. A somewhat arbitrary
100ms timeout is defined to ensure that the system doesn't lock up in
the case of an error.
Since we need to dynamically determine if we're waiting for a 0 bit or a
1 bit, it's easier to use wait_for_bit_32() than readl_poll_timeout().

which is added in a following patch.

leading to a crash when trying to probe the clocks.
