term/efi/console: Treat key.scan_code 0x0102 (suspend) as Enter

Browse Source 
Some Qualcomm-based UEFI platforms only provide volume up, volume down,
and power keys. The volume keys are already mapped to SCAN_UP and SCAN_DOWN,
while the power key is mapped to SCAN_SUSPEND (key.scan_code 0x0102).

On such devices, the power key is commonly used as the Enter (confirm)
button, since no dedicated Enter key exists. This patch treats key.scan_code
0x0102 as Enter to improve usability on these platforms.
