Add support for the NXP LPC845 Breakout board.
On this board the HIC is an LPC11U35 and the target is an LPC845, so the firmware is built from the existing lpc11u35 HIC anchor and only the board and target family layers are new. The LPC84x family shares the LPC82x IAP ROM interface (entry 0x1FFF1FF1) and IAP command model, so the LPC824 flash algorithm applies unchanged. No custom reset or unlock behavior is needed, so the generic kStub_HWReset_FamilyID stub family is used rather than a new target_reset.c. Signed-off-by: Harry Qian <huan.qian@nxp.com>
