[PATCH] ARM: dts: omap4-droid4: Allow 350mA current for USB peripherals

[Tony Lindgren <tony@atomide.com>]

Looks like we can use some USB Ethernet dongles for example if we increase
the allowed power limit.

A similar PMIC MC13783 documents maximum current limit as 350 mA in in
"Table 10-3. VUSB Regulator Main Characteristics". Since we have no
other documentation, let's use that value as the limit.
