FS#10811 - USEC_TIMER fix for nano 2G

The USEC_TIMER does not work on nano 2G.

For the user, this makes the clickwheel ‘jumpy’.

TheSeven said : “the nano2g usec timer is actually a 64bit 5usec timer. rockbox only uses the lower 32 bits, but these only seem to get updated when the high part is read.”

This patch also enable WHEEL_ACCEL as it seems to work fine.

Note: the macro is a little ugly but the operation (a»31)&1 is not optimize by gcc. So we read the 64bits and only use the lower 32 bits.
