[PATCH 1/8] mtd: rawnand: qcom: make check_flash_errors() more generic

[Gabor Juhos <j4g8y7@gmail.com>]

The function gets a 'qcom_nand_host' pointer as a parameter but it is
only used to extract the nand controller's private structure from that.
In order to make the function more generic, change the declaration to
get a 'qcom_nandc_controller' pointer directly, and update the callers
accordingly.

While at it, also change the function name to use a 'qpic_nandc' prefix.

No functional changes. This is in preparation of moving the function
into the 'qpic_common' code to allow reusing it from the 'spi-qpic-snand'
driver.
