fs/super.c: sync ro remount after blocking writers

Move sync_filesystem() after sb_prepare_remount_readonly().  If writers
sneak in anywhere from sync_filesystem() to sb_prepare_remount_readonly()
it can cause inodes to be dirtied and writeback to occur well after
sys_mount() has completely successfully.

This was spotted by corrupted ubifs filesystems on reboot, but appears
that it can cause issues with any filesystem using writeback.

msm_otg: hack to allow automatic usb host mode (externally powered)
Force ID_A (host mode + charging) on detection of proprietary charger (Apple-compatible charger with voltage on D+/D-).
Unforce ID_A on PMIC: BSV clear (detection of loss of charger).
Use charger type ACA_DOCK and allow up to 1.5A charge rate in host mode.
msm_otg: hack to allow manual usb host mode (externally powered)
Enable debugfs /sys/kernel/debug/msm_otg/mode for manual otg mode manipulation.
Always force requested mode (none, peripheral, host).
Use ID_A bit instead of ID for host mode.

Note: There are no provisions for charger detection when setting host mode manually.
