lpc2000: Removed cmd51_can_xxxxb variables.

Current flash driver can fail to write across the sector boundary.
This patch fixes "thisrun_bytes" set to "cmd51_dst_boundary" value instead of "cmd51_can_xxxxb"

Referred to SevenW's post and fix,thanks.

Tested on below listed chips.
LPC810,LPC811,LPC812,LPC824,LPC1115,LPC1343,LPC1347,LPC1227,
LPC1769,LPC1788,LPC54102,LPC4088 and LPC2388.
