power: supply: cpcap-charger: add OMAP_USB2 dependency

When CONFIG_OMAP_USB2 is set to 'm' and the charger driver is built-in,
we get this link failure:

drivers/power/supply/cpcap-charger.o: In function `cpcap_charger_probe':
cpcap-charger.c:(.text+0x48c): undefined reference to `omap_usb2_set_comparator'
drivers/power/supply/cpcap-charger.o: In function `cpcap_charger_remove':
cpcap-charger.c:(.text+0x774): undefined reference to `omap_usb2_set_comparator'

This adds a dependency to prevent that problem, while still allowing
compile-testing with the OMAP_USB2 driver completely disabled.
