arm: Add bootblock_mainboard_early_init() for pre-console initialization
On most platforms, enabling the console and exception handlers are amongst the very first things you want to do, as they help you see what's going on and debug errors in other early init code. However, most ARM boards require some small amount of board-specific initialization (pinmuxing, maybe clocks) to get the UART running, which is why bootblock_mainboard_init() (and with it almost all of the actual bootblock code) always had to run before console initialization for now. This patch introduces an explicit bootblock_mainboard_early_init() hook for only that part of initialization that absolutely needs to run before console output. The other two hooks for SoC and mainboard are moved below console_init(). This model has already proven its worth before in the tegra124 and tegra132 custom bootblocks. BRANCH=None BUG=chrome-os-partner:32123 TEST=Booted on Pinky. Compiled for Daisy, Storm and Ryu.
