pda_power: Fix build error if !CONFIG_USB_OTG_UTILS
commit 9ad63986c606c60e2e916b1b96f22991f966d9cc "pda_power: Add support for using otg transceiver events" introduces below build error if !CONFIG_USB_OTG_UTILS. CC drivers/power/pda_power.o drivers/power/pda_power.c: In function 'pda_power_probe': drivers/power/pda_power.c:322: error: 'otg_is_usb_online' undeclared (first use in this function) drivers/power/pda_power.c:322: error: (Each undeclared identifier is reported only once drivers/power/pda_power.c:322: error: for each function it appears in.) drivers/power/pda_power.c:325: error: 'otg_is_ac_online' undeclared (first use in this function) drivers/power/pda_power.c:371: error: 'otg_handle_notification' undeclared (first use in this function) make[2]: *** [drivers/power/pda_power.o] Error 1 make[1]: *** [drivers/power] Error 2 make: *** [drivers] Error 2 This patch adds #ifdef CONFIG_USB_OTG_UTILS guards at necessary places to fix build errors.
