mb/google/rex: Pulling GPIO programming early to get debug msg

This patch moves the early GPIO programming from
`bootblock_mainboard_init` to `bootblock_mainboard_early_init`.

It will help to get the early debug prints as below.

TEST=Without this CL the initial report platform information
was missing as below:

[DEBUG]  VBOOT: Loading verstage.
[DEBUG]  FMAP: Found "FLASH" version 1.1 at 0x1c04000.
[DEBUG]  FMAP: base = 0xfe000000 size = 0x2000000 #areas = 33
[DEBUG]  FMAP: area COREBOOT found @ 1c09000 (4157440 bytes)
[INFO ]  CBFS: mcache @0xfef84a00 built for 18 files, used 0x414
         of 0x2000 bytes
[INFO ]  CBFS: Found 'fallback/verstage' @0x24d240 size 0x133d0 in
         mcache @0xfef84d50

With this CL the complete bootblock serial msg is coming.
