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.
