This reverts commit 5c5f08f7fc0bee9a1bc3fbdcb7a21cfd0648ab14.
This commit hard codes GPIO for max98357a drivers at a board specific
level in the machine driver in the kernel itself. When used with a
board that properly defines the GPIO pins in ACPI there is a resource
contention over the GPIO pin and the card fails to probe.
The amplifier driver has handled this pin lookup long before the
this change landed and it the pin should continue to be owned by the
amplifier as it is specific to that component. As a result this should
be reverted.

I feel instead of reverting this complete patch we can quickly submit a
new patch set with "gpio_spk_en = NONE" for maxim codec case. As codec
driver is anyhow controlling that gpio we don't need to do it from
machine driver. We've already done that here
