This adds support for EARLY_PRINTF via the CFE console; the aim is to provide a fix for the otherwise cyclic dependency between PMU discovery and console printf/DELAY: - We need to parse the bhnd(4) core table to determine the address (and type) of the PMU/PLL registers and calculate the CPU clock frequency. - The core table parsing code will emit a printf() if a parse error is hit. - Safely calling printf() without EARLY_PRINTF requires a working DELAY+cninit, which means we need the PMU. Errors in core table parsing shouldn't happen, but lack of EARLY_PRINTF makes debugging more difficult. Approved by: adrian (mentor) Differential Revision: https://reviews.freebsd.org/D7498
