Subject: [PATCH] soc: qcom: pmic_glink: remove redundant calculation of svid

gcc with W=1 reports
drivers/soc/qcom/pmic_glink_altmode.c:223:13: error: variable ‘svid’ set but not used [-Werror=unused-but-set-variable]
223 | u16 svid;

From reviewing the code, the setting of alt_port->svid does the same calculation.
Both are not needed. For debuggablity, keep the setting of local svid.
