spi: spi-qpic-snand: make qcom_spi_ecc_engine_ops_pipelined const

Marking the qcom_spi_ecc_engine_ops_pipelined as const provides
memory protection by preventing accidental modification of critical
function pointers at runtime. It also enables memory optimization
by placing the structure in read-only sections and improves code safety
by explicitly documenting the design intent that these operations
should not change after initialization.
