arm64: dts: qcom: qcs6490-rb3gen2: Increase MCP2518FD SPI frequency to 17MHz
The MCP2518FD CAN controller is limited to 14MHz because higher SPI
frequencies are unreliable with the current SPI3 pin drive strength.
Set the SPI3 data, clock and chip-select lines to 8mA drive strength and
raise spi-max-frequency to 17MHz, the maximum allowed by the MCP2518FD
errata:
0.85 * Fosc / 2 = 0.85 * 40MHz / 2 = 17MHz
