[PATCH v4 2/4] mfd: madera-i2c: Simplify obtaining I2C match data

[Biju Das]

Simplify probe() by replacing of_device_get_match_data() and ID lookup for
retrieving match data by i2c_get_match_data().

Note:
 This patch is only compile tested.

v3->v4:
 * Updated commit header.
v2->v3:
 * Used uintptr_t for enum casting.
v1->v2:
 * Added Ack tag from Charles Keepax.
 * Dropped blank line before switch statement.
