mfd: max77541: Fix Wvoid-pointer-to-enum-cast warning

'id' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

max77541.c:176:18: error: cast to smaller integer type 'enum max7754x_ids' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

use the probe callback with the same prototype.

mfd: max77541: Add ADI MAX77541/MAX77540 PMIC Support

MFD driver for MAX77541/MAX77540 to enable its sub devices.

The MAX77541 is a multi-function devices. It includes buck converter and ADC.

The MAX77540 is a high-efficiency buck converter with two 3A switching phases.

They have same regmap except for ADC part of MAX77541.
