Replace the sdram_init() in board init and rockchip_sdram_size() in
sdram driver for all the Rockchip SoCs which enable CONFIG_RAM.

Most Rockchip socs have the ability to either map the bootrom or a sram
area to the starting address of the cpu by flipping a bit in the GRF.
Newer socs leave this untouched and mapped to the bootrom but the legacy
loaders on rk3188 and before enabled the remap functionality and the
current smp implementation in the Linux kernel also requires it to be
enabled, to bring up secondary cpus.
So to keep smp working in the kernel, mimic the behaviour of the legacy
bootloaders and enable the remap functionality.

There was still a static ram value set in the rk3188-board from the
time where we didn't have actual sdram init code.
Now the sdram init leaves the ram information in SYS_REG2 and we can
decode it similarly to the rk3288.
Right now we have two duplicates of that code, which is still ok and
doesn't really count as common code yet, but if we get a third copy
at some point from a newer soc, we should think about moving that to
a more general position.

The rk3188 needs 3 U-Boot stages: a tpl living in 1KB of sram, a spl
the resides in the rest of the sram and loads the regular U-Boot living
in regular ram.
