ARM: dts: omap4-droid4: Allow 300mA current for USB peripherals
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 300 mA in in
"Table 10-4. VBUS Regulator Main Characteristics". Since we have no
other documentation, let's use that value as the limit.
