[PATCH 1/2] mfd: tps65910: remove unused data

[PATCH 1/2] mfd: tps65910: remove unused data

[Kim, Milo]

 The 'io_mutex' is not used anywhere.
 The regmap API supports the mutex internally, so no additional mutex required.

 And 'domain' private data is unnecessary because the irq domain is
 already registered by using regmap_add_irq_chip().
