Subject: [PATCH] ath10k: increase BMI timeout
When testing a 9888 chipset NIC, I notice it often takes
almost 2 seconds, and then many times OTP fails, probably due
to the two-second timeout.
[ 2269.841842] ath10k_pci 0000:05:00.0: bmi cmd took: 1984 jiffies (HZ: 1000), rv: 0
[ 2273.608185] ath10k_pci 0000:05:00.0: bmi cmd took: 1986 jiffies (HZ: 1000), rv: 0
[ 2277.294732] ath10k_pci 0000:05:00.0: bmi cmd took: 1989 jiffies (HZ: 1000), rv: 0
So, increase the BMI timeout to 3 seconds.

Subject: [PATCH] ath10k: log when longer bmi cmds happen
This lets one have a clue that maybe timeouts are happening
when we just aren't waiting long enough.

Subject: [PATCH] ath10k: add BMI parameters to fix calibration from
DT/pre-cal
QCA99X0, QCA9888, QCA9984 supports calibration data in
either OTP or DT/pre-cal file. Current ath10k supports
Calibration data from OTP only.
If caldata is loaded from DT/pre-cal file, fetching board id
and applying calibration parameters like tx power gets failed.
error log:
[ 15.733663] ath10k_pci 0000:01:00.0: failed to fetch board file: -2
[ 15.741474] ath10k_pci 0000:01:00.0: could not probe fw (-2)
This patch adds calibration data support from DT/pre-cal
file. Below parameters are used to get board id and
applying calibration parameters from cal data.
EEPROM[OTP] FLASH[DT/pre-cal file]
Cal param 0x700 0x10000
Board id 0x10 0x8000
Tested on QCA9888 with pre-cal file.
