Qipan Li d58e9a02e1 pinctrl: sirf: add usp0_uart_nostreamctrl pin group for usp-uart without flowctrl
this patch adds the lost pin group which supports to let USP0 to simulate
a UART without hardware flow control.

Barry Song bc8d25a405 pinctrl: sirf: save the status in suspend and restore after resuming
this patch saves the status of pinctrl registers and restore them while
resuming. this makes all drivers have coherent status for pinmux after
suspending and resuming.

Barry Song 3370dc916c pinctrl:sirf:re-arch and add support for new SiRFatlas6 SoC
atlas6 is a SoC very similar with primaII, the register layput of
pinctrl is same, but the pads, groups and functions of atlas6 have
different layout with prima2, this patch
1. pull the definition of pads, groups and functions out of the
pinctrl-sirf driver,and put them into soc-specific files
2. add pads, groups and functions tables for atlas6
3. let pads, groups and functions tables become the config data of
   the related dt compatible node, so the pinctrl-sirf can support
   all SiRF SoCs with the config data as private data.

In this patch,we create a sirf dir, and let
the old drivers/pinctrl/pinctrl-sirf.c =
        drivers/pinctrl/sirf/pinctrl-prima2.c +
        drivers/pinctrl/sirf/pinctrl-sirf.c

drivers/pinctrl/sirf/pinctrl-atlas6.c is a newly created file for the
pin layout of atlas6.
