gpio: aggregator: rename 'name' to 'key' in gpio_aggregator_parse()

Rename the local variable 'name' in gpio_aggregator_parse() to 'key'
because struct gpio_aggregator_line now uses the 'name' field for the
custom line name and the local variable actually represents a 'key'.
This change prepares for the next but one commit.

No functional change.
