mb/google/brask/variants/moli: use specific gpio table by board_ver

Browse Source 
EN_PP3300_EMMC will change to GPP_A21 to meet DP++ function and it based on Moli GPIO Table_20220803.xlsx. But it will let current eMMC skus can't boot into OS, so use the board_ver to decide which gpio table return and set override_gpio_table_id2 and early_gpio_table_id2 based on Moli GPIO Table_20220803.xlsx
1. set GPP_A21 to EN_PP3300_EMMC
2. set GPP_A22 to NC
3. set GPP_E20 to DDIC_DP_CTRCLK
4. set GPP_E21 to DDIC_DP_CTRLDATA

* D1 : ISH_GP1 ==> FP_RST_ODL
* FP_RST_ODL comes out of reset as hi-z and does not have an external pull-down.
* To ensure proper power sequencing for the FPMCU device, reset signal is driven low
* early on in bootblock, followed by enabling of power. Reset signal is deasserted
* later on in ramstage. Since reset signal is asserted in bootblock, it results in
* FPMCU not working after a S3 resume. This is a known issue.
