spi: dt-bindings: nuvoton,ma35d1-qspi: Add MA35D1 SPI controller

Extend the existing MA35D1 QSPI binding to also describe the MA35D1 SPI
controller.

The SPI and QSPI controllers are separate hardware IPs. QSPI additionally
supports dual, quad and DTR transfers and a target-mode timeout function,
but these differences do not require additional controller-specific
Devicetree properties.

Both controllers expose the same Devicetree-visible resources and provide
up to two native chip-select signals. GPIO chip selects are supported
through the generic SPI controller binding. Since the MA35D1 QSPI driver
now supports GPIO chip selects, also remove the existing restriction
on cs-gpios for the QSPI compatible.

Add the nuvoton,ma35d1-spi compatible and update the binding description
and examples to cover both controllers.
