Add ISA ACPI sensor driver name support

From: Hoan Tran <[email protected]>

ACPI hwmon sensor driver name has a different format such as

	APMC0D29:00
	APMC0D29:01

compared with DTB. This patch supports this format and gives the correct device address as below

apm_xgene-isa-0000 => APMC0D29:00

Adapter: ISA adapter
SoC Temperature:  +35.0°C
CPU power:        11.00 W
IO power:         20.00 W

apm_xgene-isa-0001 => APMC0D29:01

Adapter: ISA adapter
SoC Temperature:  +33.0°C
CPU power:        13.00 W
IO power:         23.83 W
