mtd: rawnand: qcom: make nandc_set_read_loc_last() more generic

Browse Source 
The function gets a 'nand_chip' pointer as a parameter but it is
only used to extract a pointer to 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 'qcom_nandc' prefix.

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