Subject: [PATCH v3 2/4] mfd: palmas: Constify .data in OF table and {palmas,tps65917}_irq_chip

Constify .data in OF table and {palmas,tps65917}_irq_chip and replace
the variable *features->features in struct palmas_driver_data and
drop the {palmas,tps659038}_features variables and use their values
directly in the named initialization.

v2->v3:
 * Restored the OF table position and moved near to the user in patch#3.
v1->v2:
 * Moved the OF table just above its user.
 * Removed trailing comma from the terminator entry for the OF table.
