WIP: Enable DesignWare SPI for EOS S3

[kowalewskijan]

This PR:

• Adds SPI driver for EOS S3 SoC along with necessary configurations
• Enables DesignWare SPI driver for the QuickFeather board
• Adds QuickFeather target to SPI tests
• Enables NOR SPI Flash for the QuickFeather board
• Enables drivers/spi_flash sample for the QuickFeather target

Remaining work:

• EOS S3 needs custom IRQ clear (in WIC controller) for SPI which is currently not implemented, hence the SPI peripheral won't work correctly until this part is done.

missed that PR.

Is it me or the SPI IP block is DesignWare? (registers have same names)

@kowalewskijan ?

[kowalewskijan]

@tbursztyka it seems you might be right. I checked the reference manual and registers names and offsets match too. I'll try to use the spi_dw driver. Thanks for pointing it out!

@tbursztyka could you remove the stale label from this PR? I pushed some WIP code with the DesignWare configuration for EOS-S3 but still I need to work on it.
