thermal/drivers/rockchip: Fix kernel-doc warnings

Don't use "/**" to begin non-kernel-doc comments.
Convert one function description to kernel-doc format.
Prevents these kernel-doc warnings:

drivers/thermal/rockchip_thermal.c:64: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * The max sensors is two in rockchip SoCs.
drivers/thermal/rockchip_thermal.c:179: warning: expecting prototype for TSADC Sensor Register description(). Prototype was for TSADCV2_USER_CON() instead
drivers/thermal/rockchip_thermal.c:1342: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * Reset TSADC Controller, reset all tsadc registers.
