[PATCH] nvmem: airoha-smc-efuses: Fix the SMC function ID for eFuse read

[Zhengping Zhang]

The Airoha firmware uses SMC function ID 0x82000005 for the eFuse
word-read service. The driver currently uses 0x82000001, which does
not select this service and prevents eFuse read from working
correctly.

Use the correct function ID and rename the constant to
AIROHA_SMC_EFUSE_READ_WORD_FID to make the selected operation explicit.

Fixes: b7846af2e6ca ("nvmem: airoha: Add support for SMC eFUSE")
