Add an ISR for EMIF that: 1. reports details of access errors 2. takes action on thermal events Also clear all interrupts on shut-down. Pending IRQs may casue problems during warm-reset. Temperature handling: EMIF can be configured to poll the temperature level of an LPDDR2 device from the MR4 mode register in the device. EMIF generates an interrupt whenever it identifies a temperature level change between two consecutive pollings. Some of the timing parameters need to be de-rated at high temperatures. The interrupt handler takes care of doing this and also takes care of going back to nominal settings when temperature falls back to nominal levels.
