Some MT7915 calibration data consists of two parts. The first part
"eeprom" size is 0xe00. The second part "precal" size is 0x19c10.
Though some devices may not have precal data, it's better to assume
that precal data exists as no users/developers confirm it. On the
other hand, some devices definitely do not contain precal data
because the EEPROM partition size is smaller than the precal NVMEM
cell size.

Some MT7915 devices need to load the second part of the eeprom to
work properly. The mt76 driver is not yet ready to read the pre-cal
data via the NVMEM cell. Therefore, partially revert commit to fix
the device probe issue on some devices.
P.S.
Except for D-Link and Ubnt devices, It is still uncertain whether
pre-cal data is required for other devices in the patch.
This partially reverts commit 9ac891f8c4.
