ARM: dts: msm: Add support for USB HS AC/DC coupling on SA6155 



Enable USB_HS_AC_POLARITY(Active Low) and USB_HS_AC_EN bits in
TCSR_CONN_BOX_SPARE_0 register of the TCSR regs on SA8155.
Also add pinctrl changes to configure GPIOs 88 and 89 in
USB HS AC ENABLE function mode.
This is required to enable USB HS AC/DC coupling feature.
