spi: spi-qpic-snand: remove 'clr*status' members of struct 'qpic_ecc'

In the qcom_spi_ecc_init_ctx_pipelined() function, the 'clrflashstatus'
and the 'clrreadstatus' members of the ECC context gets initialized with
constant values. Then these values are used by several functions to set
the corresponding members in the register cache.

Because the values are never modified, change the code to set the those
directly in the register cache by the qcom_spi_ecc_init_ctx_pipelined()
function, and remove the repetitive code from the other functions to
reduce code duplication.

Also, remove the respective members from the 'qpic_ecc' structure as
those became unused due to the change.

No functional changes intended.
