ASoC: es8316: Handle optional IRQ assignment

[ Upstream commit 39db65a0a17b54915b269d3685f253a4731f344c ]

The driver is able to work fine without relying on a mandatory interrupt
being assigned to the I2C device. This is only needed when making use of
the jack-detect support.

However, the following warning message is always emitted when there is
no such interrupt available:

  es8316 0-0011: Failed to get IRQ 0: -22

Do not attempt to request an IRQ if it is not available/valid. This also
ensures the rather misleading message is not displayed anymore.

Also note the IRQ validation relies on commit dab472eb931bc291 ("i2c /
ACPI: Use 0 to indicate that device does not have interrupt assigned").
