[PATCH 3/8] musb: fix compilation warning in host only mode

[Ajay Kumar Gupta <ajay.gupta@ti.com>]

Fixes below compilation warning when host only configuration is
selected.
drivers/usb/musb/musb_core.c: In function 'musb_stage0_irq':
drivers/usb/musb/musb_core.c:711: warning: unused variable 'mbase'

Also removed definition of 'mbase' from multiple places to only
at function top.
