Add ISA ACPI sensor driver name support

Browse Source 
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
