[PATCH] v1.88 DM04/QQBOX Move remote to use rc_core dvb-usb-remote.

[Malcolm Priestley <tvboxspy@gmail.com>]

driver to use dvb-usb-remote.
The remote(s) generates 24 bit NEC codes, lme2510 keymaps redefined.
 
Other minor fixes
fix le warning.
make sure frontend is detached on firmware change.  

applied to v1.86
