pcengines/apu2: Switch away from ROMCC_BOOTBLOCK

Add early SuperIO initialization in bootblock to enable early console.
Also, remove some southbridge-specific initialization that has been
moved to southbridge bootblock initialization in previous patch.

The board obtains few additional timestamps: start of bootblock, end
of bootblock, starting to load romstage and finished loading romstage.

TEST=boot apu2 and launch Debian with Linux kernel 4.14.50
