edac, highbank: Improve and unify naming

Assinging correct names of the 'hb_mc_edac' and 'hb_l2_edac' edac
modules for module, controller and device. Reported values for
Highbank in dmesg are now:

EDAC MC0: Giving out device to module hb_mc_edac controller
calxeda,hb-ddr-ctrl: DEV fff00000.memory-controller (INTERRUPT)

EDAC DEVICE0: Giving out device to module hb_l2_edac controller
calxeda,hb-sregs-l2-ecc: DEV fff3c200.sregs (INTERRUPT)
