[PATCH v2 1/2] soc: mediatek: mtk-svs: Commonize t-calibration-data fuse array read

[Nícolas F. R. A. Prado]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno at collabora.com>

Commonize the repeating pattern for reading the "t-calibration-data"
efuse data in a new function svs_thermal_efuse_get_data(), reducing
the size of this driver.

No functional changes.
