Current imx7d-sdb.dts has some incorrect settings about
Rev-A and Rev-B boards, some of the settings are based on
Rev-A board but some are based on Rev-B board, clean up it
by adding i.MX7D SDB Rev-A board support, make default
imx7d-sdb.dts for Rev-B board as usual, and introduce
imx7d-sdb-reva.dts for Rev-A board. Below are the affected
differences of Rev-A and Rev-B board:

                Rev-A           Rev-B
USB_OTG2_PWR:   UART3_CTS_B     GPIO1_IO07
ENET_EN_B:      None            GPIO1_IO04
TP_INT_B:       EPDC_DATA13     EPDC_BDR1

change since V1:
	remove "pinctrl-assert-gpios" which is unused in upstream, and use phy-supply
to control fec2's enable pin, model the enable pin as GPIO regulator.

Instead of using hog group, this should be defined by pinctrl entry to
be referred by the fixed regulator that uses this GPIO?
