dra72-evm-common.dtsi consolidates dra72-evm.dts and dra72-evm-revc.dts
which also include tps65917 pmic support as both the evms uses the same
pmic. But, dra71-evm has mostly similar features with a different pmic.
In order to exploit dra72-evm-common.dtsi, creating a separate dtsi
for tps65915 support and including it in respective board files.

This patch breaks USB XHCI and boot on dra72-evm (both revC and non revC)

I'll explain why below.

Hmm.. Thanks for catching it. I remember it was booting when I tested,
not sure how I missed this :(. usb2_phy1 & 2, mmc and dss supplies needs
to be added in dra72-evm-tps65917.dtsi file.

OK.

Tony,
	Do you want me to resend this patch or fixup patch on top of this?

In case you send a new patch. please add
