spi: tegra210-quad: Refactor error handling into helper functions

Browse source

Extract common cleanup code into dedicated helper functions to simplify
the code and improve readability. This refactoring includes:

- tegra_qspi_reset(): Device reset and interrupt cleanup
- tegra_qspi_dma_stop(): DMA termination and disable
- tegra_qspi_pio_stop(): PIO mode disable

No functional changes. This is purely a code reorganization to prepare
for improved timeout handling in subsequent patches.
