TMS4570: Was not building arm_head.S or up_allocateheap.c; ARMv7-R: Fix variious problems not that arm_head.S is being built

STM32 PWM: Fix timer type bug

ARMv7-R: Add a configuration to support delayed memory initialization.  This logic was already in place for SDRAM but is also required for some ECC memories as well.

ARMv7-R: Add logic to work-around errata, remove logic to access VBAR since this is no VBAR and add logic to access PMCR.  TMS570: Add logic to set debug bits in PMCR

TMS570:  Memory map applies only to LS04x and LS03x.  Peripheral numbering seems to start with 1, not 0
