mb/google/zork: Drop unnecessary PULL_UPs for trembyle reference

This change drops internal pulls for trembyle reference configured on pads
which already have external pull-ups in hardware.

GPIO_0(PWR_BTN_L): Pulled up to PP3300_A
GPIO_2(WAKE_L): Pulled up to PP3300_A
GPIO_10: Unused. Changed to PAD_NC.
GPIO_12(USI_INT_ODL): Pulled up to PP3300_A
GPIO_16(USB_OC0_L): Pulled up to PP3300_A
GPIO_17(USB_OC1_L): Pulled up to PP3300_A
GPIO_21(EMMC_CMD): Pulled up to PP3300_A
GPIO_22(EC_FCH_SCI_ODL): Pulled up to PP3300_A
GPIO_31(EC_AP_INT_ODL): Pulled up to PP1800_A
GPIO_90: Unused. Changed to PAD_NC.
GPIO_113(I2C2_SCL): Pulled up to PP3300_S0
GPIO_114(I2C2_SDA): Pulled up to PP3300_S0
GPIO_129(KBRST_L): Pulled up to PP1800_S0
GPIO_130(EC_IN_RW_OD): Pulled up to PP3300_S0
GPIO_92(CLK_REQ0_L): Pulled up to PP3300_S0
GPIO_115(CLK_REQ1_L): Pulled up to PP3300_S0
GPIO_132(CLK_REQ4_L): Pulled up to PP3300_S0
