mfd: omap-usb-tll: Fix register offsets
gcc-8 notices that the register number calculation is wrong
when the offset is an 'u8' but the number is larger than 256:
drivers/mfd/omap-usb-tll.c: In function 'omap_tll_init':
drivers/mfd/omap-usb-tll.c:90:46: error: overflow in conversion from 'int' to 'u8 {aka unsigned char}' chages value from 'i * 256 + 2070' to '22' [-Werror=overflow]
This addresses it by always using a 32-bit offset number for
the register. This is apparently an old problem that previous
compilers did not find.
Fixes: 16fa3dc75c22 ("mfd: omap-usb-tll: HOST TLL platform driver")
