regulator: act8945a: fix non-kernel-doc comments

Don't use kernel-doc "/**" markers for comments that are not in
kernel-doc format. This prevents these warnings:

drivers/regulator/act8945a-regulator.c:19: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * ACT8945A Global Register Map.
drivers/regulator/act8945a-regulator.c:50: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * Field Definitions.
drivers/regulator/act8945a-regulator.c:56: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * ACT8945A Voltage Number
