USB: mpq8092_defconfig: defconfig for USB

Add necessary defconfig changes for initial
USB peripheral.

Android gadget driver supports multiple USB
functions and uses different interfaces to
support the same.
- CONFIG_DIAG_CHAR for USB Diag function,
- CONFIG_SOUND, CONFIG_SND and CONFIG_SND_SOC for USB Audio function,
- CONFIG_USB_GADGET and CONFIG_USB_G_ANDROID for USB Android Gadget
driver,
- CONFIG_USB_GADGET_DEBUG_FILES and CONFIG_USB_GADGET_DEBUG_FS for USB
Gadget debug support,
- CONFIG_USB_CI13XXX_MSM for USB Device Controller driver.

Hence enable all above config to get USB enumeration and (DIAG + ADB)
composition with 8092 simulator.
