apm821xx: speed up ath9k-caldata extraction
Reading and writing to and from flash storage is slow and currently,
the ath10kcal_extract() scripts are even more at an disadvantage
because they use a block size of 1 to be able skip.
This patch reworks the extraction scripts to be much faster and
efficient by reading and writing the calibration data in possibly
one big block.
