[PATCH] usb: phy-generic, phy-ulpi patch set

This patch set add support 
* GPIO ChipSelect
* ULPI support to set VBUS flags for EXTVBUSIND,CHRGVBUS
* ULPI support to set VBUS flags from DT

[PATCH 1/3] usb: phy-generic: Add GPIO based ChipSelect
	The ULPI ISP1504 uses the CHIP_SELECT_N (low active) pin to active the
	chip. This patch add support for GPIO based ChipSelect almost the same
	way implemented for the Reset feature.

[PATCH 2/3] usb: phy-ulpi: Add EXTVBUSIND,CHRGVBUS flag support
	ULPI like ISP1504 support external vbus power indication
	used in combination with vbus switches mic2075.

[PATCH 3/3] usb: phy-generic: Add ULPI VBUS support
	Some platforms need to set the VBUS parameters of the ULPI
	like ISP1504 which interact with overcurrent protection and
	power switch MIC2575. Therefore it requires to set
	* DRVVBUS
	* DRVVBUS_EXT
	* EXTVBUSIND
	* CHRGVBUS
