mfd: Add pca9440 register map ...

The pca9440 is a PMIC found on the i.MX8MP-EVK board. This adds the
register map for it.

fs: fat: extend for in-PBL support ...

The AT91 BootROM loads a boot.bin file from the first FAT partition
into SRAM, when booting from MMC. To avoid the need for two barebox
configurations for each of the bootloader stages, add PBL support
for reading from FAT. This way each stage need only have a different
PBL entry point.

pbl: add block I/O API ...

We already have some PBL MCI implementations in barebox, but none
are used for chainloading a barebox from a file system.

There are some SoCs that would benefit from this however:
At least the Zynq, AT91, SoCFPGA and TI SoCs.

In preparation for supporting first stage boot on these where it's
customary for both the BootROM and first stage bootloader to load the
follow-up stage from FAT, add a very basic block I/O API that MCI
drivers can implement.

clk: sync of_clk_get_parent_name with upstream ...

Upstream of_clk_get_parent_name only resorts to node name as a fallback.
Instead, it uses the name supplied for registered clocks whenever
possible. On the sama5d2, this results in sckc@f8048050 and slowck,
respectively. So far, sckc@f8048050 in the parents array couldn't be
matched with any existing clock, leading to an inaccurate clock tree.

Port over the v5.8-rc1 state of the function to fix this.

fastboot: Drop support for downloading to buffer ...

The option to download to a buffer instead of a file was introduced
because in some workloads it is required to have a contiguous image
in memory. With recent changes now ramfs can provide such a buffer
via memmap API even when it downloaded the data to a file. This makes
the explicit download to buffer option unnecessary, so remove it.

common: elf: load elf directly from file ...

Currently, elf file must be loaded into a buffer and then passed to
elf_load_image. This requires to copy the whole elf file before booting
it. This commit allows to pass the filename directly and will allocate
data only for the elf header (elf header + program headers). This will
then be used to load the elf data from the file without copying it in an
intermediate buffer. Elf segments are first parsed into a list and are
then loaded from the file in a second time.
