spi: spi-qpic-snand: avoid writing QPIC_EBI2_ECC_BUF_CFG register
The description of commit bfb34eced559 ("mtd: rawnand: qcom: avoid writing
to obsolete register") says this:
"QPIC_EBI2_ECC_BUF_CFG register got obsolete from QPIC V2.0 onwards.
Avoid writing this register if QPIC version is V2.0 or newer."
Although the referenced commit is related to the 'qcom-nandc' driver,
however the hardware supported by the current driver is also based on
QPIC v2.0 so we should avoid writing that register here as well.
Remove the register writing code to avoid undefined behaviour.
