[ECOS] Re: eCos on SE7751R board

[Paul van Gool <paul dot vangool at rinconnetworks dot com>]

I forgot to mention there are also a few changes to
packages/hal/sh/se7751r/v2_0/include/platform.inc (when compared to
packages/hal/sh/se7751/v2_0/include/platform.inc):

CYGARC_REG_WCR2
CYGARC_REG_RTCOR
CYGARC_REG_MCR
