Add SPI driver that initializes SPI regmap for the adxl345 core driver.
The driver supports the same functionality as I2C namely the x, y, z and
scale readings.
Portion of minor comments.

Same question. Would it be just

depends on INPUT_ADXL34X=n

?

GENMASK(7, 6) ?
True, but I would like to keep this as is. It is more readable and
obvious than GENMASK().

Reverse order.

And usually we do assignments from function parameters first.
Ack.

Thanks,

Ugly casting!
