Subject: [PATCH] rtw88: 8723d: Add DIG parameter
Git-commit: db39a9ddacada1e4c065d894faa3fa0e1100b10d
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430, bsc#1176741
To improve user experience in field, we need DIG to adjust RX initial gain
depends on field situation. Since each chip has its own register address,
this commit defines 8723d specific address.
