rockchip: clk: rk3368: implement DPLL (DRAM PLL) support

To implement a TPL stage (incl. its DRAM controller setup) for the
RK3368, we'll want to configure the DPLL (DRAM PLL).

This commit implements setting the DPLL (CLK_DDR) and provides PLL
configuration details for the common DRAM operating speeds found on
RK3368 boards.

rockchip: clk: rk3368: do not change CPLL/GPLL before returning to BROM

The RK3368 has a somewhat temperamental BootROM (which I learned the
hard way) when it comes to reconfiguring the CPLL and GPLL (in fact,
experiments show that changing the GPLL broke things for me, while
changing the CPLL seems to be more benign).  These should not be
modified by the SPL stage, if we intend to return to the BootROM for
chain booting the next stage.

This commit changes the clock initialisation to not change CPLL/GPLL
before returning to the BootROM (i.e. in TPL).  As it's safe to change
these settings if we no longer intend to return to U-Boot, we'll run
the full PLL setup a little later (i.e. in SPL).

rockchip: back-to-bootrom: add 'back-to-bootrom' support for AArch64

The back-to-bootrom support for Rockchip is equivalent to an
(assembly) implementation of setjmp/longjmp (i.e. it saves the
stack-pointer, link-register and callee-saved registers). Up until
now, this had only been implemented for AArch32 (i.e. ARMv7 or older),
which puts the new ARMv8 devices (which boot in AArch64 mode) at a
slight disadvantage.

To allow use of the 'back-to-bootrom' feature on new devices (e.g. the
RK3368), this commit adds an implementation for AArch64.

spl: configure 'return to bootrom' separately for SPL and TPL

On the RK3368, we want our TPL to use the 'return to bootrom' boot
method (to have the bootrom load up the SPL stage) and then continue
with different boot methods (MMC, SPI, etc.) from SPL.

This adds the config option needed to control the availabily of the
'return to bootrom' boot-method separately for the TPL stage.

spl: add a 'return to bootrom' boot method

Some devices (e.g. the RK3368) have only limited SRAM, but provide
support for loading the next boot stage after our SPL performs basic
setup (e.g. DRAM).

For target systems like these, we add a boot device BOOTROM that will
invoke a board-specific hook to return to the bootrom (if supported).
