Turn data cache on

Browse Source 
This fixes https://github.com/hathach/tinyusb/issues/1894.  I'm not really
sure if this is the correct way to fix it, and I have not tested on all the
rest of the family members, however, this lets the i.MX1010 work again.

The problem:  the latest SDK update does not enable the data cache by default
This causes an assert in board_init() when attemping to control clock
gating.  I haven't investigated further as to *why* it's a problem, but it
is a problem.
