This fixes the dme-reset failed when doing recovery. Because device
reset is not enough, we could occasionally see the error below:
ufshcd-rockchip 2a2d0000.ufs: uic cmd 0x14 with arg3 0x0 completion timeout
ufshcd-rockchip 2a2d0000.ufs: dme-reset: error code -110
ufshcd-rockchip 2a2d0000.ufs: DME_RESET failed
ufshcd-rockchip 2a2d0000.ufs: ufshcd_host_reset_and_restore: Host init failed -110
Fix this by resetting the controller on PRE_CHANGE stage of hce enable
notify.

RK3576 SoC contains a UFS controller, add initial support for it.
The features are:
1. support UFS 2.0 features
2. High speed up to HS-G3
3. 2RX-2TX lanes
4. auto H8 entry and exit
Software limitation:
1. HCE procedure: enable controller->enable intr->dme_reset->dme_enable
2. disable unipro timeout values before power mode change
[mkp: fix build errors]
