Synchronize device tree bindings with v5.5-rc6 tag with commit id
"b3a987b0264d".

Also, it removes older clock binding defined for S900 along with undocumented
compatible string "actions,s900-serial" from serial driver and adapts clock
driver to cater to new bindings.

The free() function checks if its argument is NULL. We should avoid
checking for NULL before calling free like in

    if (result->tds)
        free(result->tds);

The list of relevant functions differs between Linux and U-Boot, e.g. we
use free().

Adjust the list of relevant functions.

Commit 6293b036 ("mtd: nand: pxa3xx: add raw read support") added the
local data_len variable in handle_data_pio() to track read size, but
forgot to update the condition of drain_fifo() call. That happens to
work when the layout last_chunk_size != 0. But when last_chunk_size ==
0, drain_fifo() is not called to read the last chunk, which leads to
"Wait timeout!!!" error. Fix this.

Reviewed-by: NSimon Glass <sjg@chromium.org>

As a preparation for turning reserve_mmu into an arch-specific variant,
introduce arm_reserve_mmu on ARM. It implements the default routine for
reserving memory for MMU TLB and needs to be weakly defined in order to allow
for machines to override it.

Without this decoupling, after introducing arch_reserve_mmu, there would be two
weak definitions for it, one in common/board_f.c and one in
arch/arm/lib/cache.c.

When moving the PHYLIB PHY drivers around in Kconfig we did not at the
