iio: adc: ti_am335x_adc: allocating too much in probe

Browse Source 
commit 5ba5b437ef upstream.

We should be allocating enough information for a tiadc_device struct
which is about 400 bytes but instead we allocate enough for a second
iio_dev struct which is over 2000 bytes.

Fixes: fea89e2dfc ("iio: adc: ti_am335x_adc: use variable names for sizeof() operator")
