There is no real reason to keep the bit-definitions for the IOMUX in
the grf header file (which defines the register layout of the GRF block):
these should only be used by our pinctrl driver (with the possible
exception of early debug-init code in TPL/SPL).
This moves the relevant definitions from the grf_rk3368.h header
into the pinctrl driver pinctrl_rk3368.c.

The RK3368 GRF header was still defines with a shifted-mask but with
non-shifted function selectors for the IOMUX defines. As the RK3368
support is still fresh enough to allow a quick change, we do this now
before having more code use this.

On the RK3368 we use a TPL-stage similar to Rockchip's DDR init
(i.e. it initialises DRAM, leaves some info for the next stage and
returns to the BootROM). To allow compatibility with Rockchip's DDR
init code, we use the same register os_reg2 in pmugrf for passing
this info (i.e. DRAM size and configuration) between stages.
This change adds the definitions for os_reg[0] through os_reg[3] to
the pmugrf structure for the RK3368.

Add sdram driver in U-Boot for get the correct sdram size from
sys_reg, so that U-Boot can co-work with Rockchip loader or SPL
to get different dram capability and then tell the kernel.
