c72f4d4c2e ARM: uniphier: add PLL init code for LD11 SoC
- Initialize PLLs (SPL initializes only DPLL to save the precious
   SPL memory footprint)
 - Adjust CPLL/MPLL to the final tape-out frequency
 - Set the Cortex-A53 clock to the maximum frequency since it is
   running at 500MHz (SPLL/4) on startup

682e09ff9f ARM: uniphier: add PLL init code for LD20 SoC
Initialize the DPLL (PLL for DRAM) in SPL, and others in U-Boot
proper.  Split the common code into pll-base-ld20.c for easier
re-use.

6a3e4274e4 ARM: uniphier: move PLL init code to U-Boot proper where possible
The PLL for the DRAM interface must be initialized in SPL, but the
others can be delayed until U-Boot proper.  Move them from SPL to
U-Boot proper to save the precious SPL memory footprint.

b78ffc53c5 ARM: uniphier: move XIRQ pin-mux settings of LD11/LD20
This is the last code in the mach-uniphier/pinctrl/ directory.
Push the remaining code out to delete the directory entirely.

5ac9dfbe9d ARM: uniphier: consolidate NAND pin-mux settings
The NAND subsystem has not supported the Driver Model yet, but the
NAND pin-mux data are already in the pinctrl drivers.  Use them by
calling pinctrl_generic_set_state() directly.

b291671232 ARM: uniphier: merge board init functions into board_init()
Currently, the UniPhier platform calls several init functions in the
following order:

  [1] spl_board_init()
  [2] board_early_init_f()
  [3] board_init()
  [4] board_early_init_r()
  [5] board_late_init()

The serial console is not ready at the point of [2], so we want to
avoid using [2] from the view point of debuggability.  Fortunately,
all of the initialization in [2] can be delayed until [3].  I see no
good reason to split into [3] and [4].  So, merge [2] through [4].
