lib: fdt: Introduce fdtdec_setup_mem_size_base_lowest()

New function should be called from board dram_init() because it initialized
gd->ram_base/ram_size. It finds the lowest available memory.

On systems with multiple memory nodes finding out the first memory node by
fdtdec_setup_mem_size_base() is not enough because this memory can be above
actual U-Boot VA mapping. Currently only mapping till 39bit is supported
(Full 44bit mapping was removed by commit 7985cdf74b28 ("arm64: Remove
non-full-va map code")).
If DT starts with the first memory node above 39bit address then system can
be unpredictable.

The function is available only when multiple memory bank support is
enabled.

Calling fdtdec_setup_memory_banksize() from dram_init() is not possible
because fdtdec_setup_memory_banksize() is saving dram information to bd
structure which is placed on stack but not initialized at this time. Also

Origin function was calling strsep which replaced delimiter ',' by a null

following behavior:

ZynqMP>  printenv fdtfile

ZynqMP> fdt addr $fdtcontroladdr
ZynqMP> fdt print / compatible
compatible = "xlnx", "zynqmp"

As is visible fdtfile was correctly composed but a null byte caused that
xlnx was separated from zynqmp.
This hasn't been spotted because in all Xilinx DTs there are at least 3
compatible string and only the first one was affected by this issue.
But for systems which only had one compatible string "xlnx,zynqmp" it was
causing an issue when U-Boot's DT was used by Linux kernel.

The patch removes strsep calling and strchr is called instead which just
locate the first char after deliminator ',' (variable called "name").
And using this pointer in fdtfile composing.
