[PATCH v6 03/11] iio: dac: mcp47feb02: use field_get() instead of custom dynamic macros

[Ariana Lazar <ariana.lazar@microchip.com>]

Replace manual bit operations which select channel corresponding bits
from a control register in mcp47feb02_init_ctrl_regs() with field_get()
macro used with masks already defined for regmap operations within the
driver.
