usb: musb: Remove platform context save/restore API
For OMAP3 and OMAP4 for offmode and retention support, musb sysconfig is configured to force idle and standby with ENABLE_FORCE bit of OTG_FORCESTNDBY set. And on wakeup configure to no ilde/standby with resetting the ENABLE_FORCE bit. There is not need to save and restore of this register anymore so removed omap2430_save_context/omap2430_restore_context functions. and also removed otg_forcestandby member of musb_context_registers structure Signed-off-by: Hema HK <hemahk@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
