Usually the digital and analog phys use the same reference clock,
but some platforms have two separate reference clocks for each of
them, so add another optional clock to support them.
In order to keep the clock names consistent with PHY IP's, change
the da_ref for analog phy and ref clock for digital phy.

Malloc gets initialized with a call to mem_malloc_init() with the address
the allocation starts to and its size. Currently it is not possible to
move the malloc from one memory area to another as the malloc would eventually
fail.

This patch adds in the ability to re-init the malloc with the updated
start address and the size.

One of the use cases of this feature is SPL U-Boot running from within
the static memory and calling to malloc init from within board_init_f():

	arch/arm/cpu/armv8/start.S:reset vector
	arch/arm/cpu/armv8/start.S:main()
	arch/arm/lib/crt0_64.S:board_init_f()
	board/<my_board>/common/spl.c:board_init_f()
        board/<my_board>/common/spl.c:mem_malloc_init((ulong)CONFIG_SYS_SPL_MALLOC_START,
                        CONFIG_SYS_SPL_MALLOC_SIZE);

Shortly after the DDR (main) memory is init and ready we call to malloc init
again but this time with the start address in the DDR memory and a much greater
size for moving the allocation off the static to the DDR memory:

	board/<my_board>/common/spl.c:mem_malloc_init((ulong)CONFIG_SPL_MALLOC_OFFSET,
			CONFIG_SPL_MALLOC_SIZE);

Where CONFIG_SYS_SPL_MALLOC_START and CONFIG_SPL_MALLOC_OFFSET are the start
addresses of the malloc in the static and DDR memories respectively and
CONFIG_SYS_SPL_MALLOC_SIZE=SZ_16K and CONFIG_SPL_MALLOC_SIZE=SZ_2M are
the sizes of the mallocs in these memories. Note, now we have a much greater
memory, enlarging from 16K to 2M, available for allocation.

There is an alternative approach already existing in U-Boot with the use of
an early (simplified) malloc and the proper (dlamalloc) malloc however
necessitating managing the two mallocs whereas this approach proposes using
a single dlmalloc.

The signature check on config node is broken on fit with padding.
To compute the signature for config node, U-Boot compute the
signature on all properties of requested node for this config,
except for the property "data". But, when padding is used for
binary in a fit, there isn't a property "data" but two properties:
"data-offset" and "data-size". So to fix the check of signature,
we also don't use the properties "data-offset" and "data-size"
when checking the signature on config node.

The cmdline for calling the dtc was cut-off when using long filenames (e.g.

For FIT-images cmd[MKIMAGE_MAX_DTC_CMDLINE_LEN] is declared (hardcoded 512 bytes),
and contains some static values, the path of a tmpfile and a datafile. tmpfile is
max MKIMAGE_MAX_TMPFILE_LEN (256) and datafile might be also this size. Having two
very long pathname results in a truncation os the executed shell command, as the
truncated datafile path will not be found.
Redefine MKIMAGE_MAX_DTC_CMDLINE_LEN to "2 * MKIMAGE_MAX_TMPFILE_LEN + 35 for the
parameters.
This likely applies to the "-d" parameter, too.

Solved the overflow on phys_addr_t type for start + size in
mmu_set_region_dcache_behaviour() function.

This overflow is avoided by dividing start and end by 2 before addition,
and we only expecting that start and size are even.

This patch doesn't change the current function behavior if the
parameters (start or size) are not aligned on MMU_SECTION_SIZE.

For example, this overflow occurs on ARM32 with:
start = 0xC0000000 and size = 0x40000000
then start + size = 0x100000000 and end = 0x0.

For information the function behavior change with risk of regression,
if we just shift start and size before the addition.
Example with 2MB section size:
  MMU_SECTION_SIZE 0x200000 and MMU_SECTION_SHIFT = 21
  with start = 0x1000000, size = 0x1000000,
  - with the proposed patch, start = 0 and end = 0x1 as previously
  - with the more simple patch:
    end = (start >> MMU_SECTION_SHIFT) + (size >> MMU_SECTION_SHIFT)
    the value of end change:
    start >> 21 = 0, size >> 21 = 0 and end = 0x0 !!!

This patch allow to use the generic weak function dram_bank_mmu_setup
