usb: musb-new: add Allwinner F1C100s support

Browse source 
The Allwinner F1C100s SoC has a MUSB controller like the one in the A33,
but needs an SRAM region to be claimed like the A10. We do the latter
anyway, even on chips that don't need it, so there is no real difference
in our compatible string matching.

Add a mapping between the config struct used in the Linux to our
requirements here on the way.

* .hdrc_config:
* sunxi_musb_hdrc_config_5eps => musb_config
* sunxi_musb_hdrc_config_4eps => musb_config_h3
* .has_sram: always enabled, ideally no-op on SoCs not using it
