Currently U-Boot SPL prints just generic message "2 GiB left unmapped".
Change it to more detailed "2 GiB of DDR memory left unmapped in U-Boot".
This is just U-Boot configuration and operating system may map more (or
also less) memory.

U-Boot core code already handles the case when RAM size is bigger than
CONFIG_MAX_MEM_MAPPED. So there is no need to do duplicate check in fsl ddr
driver for CONFIG_MAX_MEM_MAPPED. Instead simplify code to just check if
RAM size can be representable in phys_size_t type. And avoid printing
warning if phys_size_t is just 1 byte smaller than RAM size, which is the
typical situation with 4 GB DDR module.

Function fsl_ddr_compute() always return size in unsigned long long type,
but function fsl_ddr_sdram_size() returns size in phys_size_t type.
When 36-bit addressing mode is not enabled then phys_size_t type is only
32-bit and thus it cannot store value 4GB (0x100000000). Function
fsl_ddr_sdram_size() in this case returns truncated value 0x0.
Fix this issue by returning the highest representable value, which is
0xffffffff (4GB - 1 byte).
This change fixes crashing of proper U-Boot because it detected 4 GB module
as RAM with zero size.

Check needs to be done against CONFIG_MAX_MEM_MAPPED macro and not fixed
size 4GB (as CONFIG_MAX_MEM_MAPPED can be lower and for example for e500
cores it is just 2GB). Also fix printf re-align, which should be applied
only for non-SPL builds, during init_dram() call.

The mtk clock framework in u-boot uses array index for searching clock
parent (kernel uses strings for search), so we need to specify a special
clock with ID=0 for CLK_XTAL in u-boot.
In the mt7622/mt7629 clock tree, the clocks with ID=0 never call
mtk_topckgen_get_mux_rate, adn return xtal clock directly. This what we
expected.
However for newer chips, they may have some clocks with ID=0 not
representing the xtal clock and still needs mtk_topckgen_get_mux_rate be
called. Current logic will make entire clock driver not working.
This patch adds a flag to indicate that whether a clock driver needs clocks
with ID=0 to call mtk_topckgen_get_mux_rate.

This feature set includes the important update on PIO4 pinctrl driver
that solves a long time mismatch between Linux and U-boot, related on
the unification of pinctrl and gpio driver support, now respecting the
pinctrl bindings ABI; and also support for pinctrl subnodes. The feature
set also adds support for PDA screen detection for sam9x60_curiosity

board specific enabling is not needed any more. This patch sync's these
