mb/google/brya: Enable ACPI S3 sleep state support

Browse source 
Add missing HAVE_ACPI_RESUME Kconfig selection to enable S3
(suspend-to-RAM) sleep state support on Brya-based boards.

Without this option, the ACPI sleepstates.asl initializes SSFG to
0x09 (supporting only S0 and S4) instead of 0x0D (supporting S0, S3,
and S4). This prevents the _S3 ACPI object from being created in the
DSDT, causing the operating system to not recognize S3 as an
available sleep state.

With this change:
- SSFG is initialized to 0x0D
- _S3 ACPI object is created in DSDT
- Linux recognizes S3 as supported (dmesg shows "ACPI: PM: (supports
  S0 S3 S4 S5)")
- Both s2idle and deep sleep options become available

Tested on Yaviks (Nissa/PCH-N variant).
