[PATCH v2 3/3] iio: frequency: ad9523: fix checkpatch warnings for symbolic permissions

[bhargav]

The driver currently defines device attributes using
symbolic permission flags (S_IRUGO and S_IWUSR).
Update these to use octal permissions (0444 and 0200) to resolve
checkpatch warnings.

Changes in v2:
- It was suggested in v1 to convert these to 
  IIO_DEVICE_ATTR_RO() and _WO(). However, those helper macros 
  expect uniquely named callbacks (e.g. pll1_locked_show), 
  whereas this driver uses shared multiplexed callbacks 
  (eg. ad9523_show). Converting to the helpers would require 
  generating wrapper functions. 
  Therefore, this v2 keeps IIO_DEVICE_ATTR but updates the 
  permissions to standard octal format.
