pinctrl: samsung: Allow grouping multiple pinmux/pinconf nodes

One of remaining limitations of current pinctrl-samsung driver was
the inability to parse multiple pinmux/pinconf group nodes grouped
inside a single device tree node. It made defining groups of pins for
single purpose, but with different parameters very inconvenient.

This patch implements Tegra-like support for grouping multiple pinctrl
groups inside one device tree node, by completely changing the way
pin groups and functions are parsed from device tree. The code creating
pinctrl maps from DT nodes has been borrowed from pinctrl-tegra, while
the initial creation of groups and functions has been completely
rewritten with following assumptions:
 - each group consists of just one pin and does not depend on data
   from device tree,
 - each function is represented by a device tree child node of the
   pin controller, which in turn can contain multiple child nodes
   for pins that need to have different configuration values.

Device Tree bindings are fully backwards compatible. New functionality
can be used by defining a new pinctrl group consisting of several child
nodes, as on following example:

sd4_bus8: sd4-bus-width8 {
part-1 {
samsung,pins = "gpk0-3", "gpk0-4",
"gpk0-5", "gpk0-6";
samsung,pin-function = <3>;
samsung,pin-pud = <3>;
samsung,pin-drv = <3>;
};
part-2 {

usb: usb5303: add support for reference clock specified in device tree

USB3503 chip supports 8 values of reference clock. The value is
specified by REF_SEL[1:0] pins and INT_N line. This patch add support
for getting 'refclk' clock, enabling it and setting INT_N line according
to the value of the gathered clock. If no clock has been specified,
driver defaults to the old behaviour (assuming that clock has been
specified by REF_SEL pins from primary reference clock frequencies
table).
