spi: tegra210-quad: Fix X1_X2_X4 encoding and support x4 transfers

commit dcb06c638a1174008a985849fa30fc0da7d08904 upstream.

This patch corrects the QSPI_COMMAND_X1_X2_X4 and QSPI_ADDRESS_X1_X2_X4
macros to properly encode the bus width for x1, x2, and x4 transfers.
Although these macros were previously incorrect, they were not being
used in the driver, so no functionality was affected.

The patch updates tegra_qspi_cmd_config() and tegra_qspi_addr_config()
function calls to use the actual bus width from the transfer, instead of
hardcoding it to 0 (which implied x1 mode). This change enables proper
support for x1, x2, and x4 data transfers by correctly configuring the
interface width for commands and addresses.

These modifications improve the QSPI driver's flexibility and prepare it
for future use cases that may require different bus widths for commands
and addresses.
