rk3308: fix drive-strength-s both for "/" and "/pinctrl" nodes

New version for linux may require the dt node build as device link, the
old dt format as following

/ {
module-A {
pinctrl-0 = <&ref_foo>;
};
pcfg-s {
pcfg_foo: pcfg-foo {
// pcfg property
};
};
pinctrl {
ref_foo: ref-foo {
rockchip,pins = <xx &pcfg_foo>;
};
};
};

This format can work well for linux under v4.19 but not for v5.10, so
this patch should fix to match modify from dt file which modified by
linux patch. the new dt format as following

/ {
module-A {
pinctrl-0 = <&ref_foo>;
};
pinctrl {
pcfg_foo: pcfg-foo {
// pcfg property
};
ref_foo: ref-foo {
rockchip,pins = <xx &pcfg_foo>;
};
};
};

The rk3308b and rk3308bs nand flash id has two group iomuxs.

The maskrom only config the iomux register in the low address,
but the kernel routing to the another one, so configure it in
spl early to avoid losing the flash iomux.
