lpc2000: Improve lpc2000 flash driver.
This patch adds flash programming support for LPC5410x and LPC82x. And adds auto flash size detection for LPC800 series. Tested on below listed boards/chips. LPC54102(LPCLPC54102Xpresso) LPC824(LPCXpresso824-MAX) LPC812(LPC812MAX) LPC811,LPC810 Change-Id: Ie68b6d425b17ccfa83814607ee61056e99800c1c Signed-off-by: Nemui Trinomius <nemuisan_kawausogasuki@live.jp> Reviewed-on: http://openocd.zylin.com/2442 Tested-by: jenkins Reviewed-by: Spencer Oliver <spen@spen-soft.co.uk> Reviewed-by: Paul Fertser <fercerpav@gmail.com>__archive__
