Backport riscv kconfig for v6.6

Backport riscv kconfig for v6.6

[Nam Cao]

Hi,

Please backport 78a03b9f8e6b ("riscv: Kconfig: Add select ARM_AMBA to
SOC_STARFIVE") to v6.6

Without this, it is not possible to configure the kernel with SPI drivers
for the Visionfive 2 board.

This one depends a1a5f2c88725 ("dmaengine: pl330: rename _start to prevent
build error"), which is already in stable.

It should be backported to v6.1 too, but it does not apply cleanly. So I
will send a patch for that.

Best regards,
Nam

Is it?  There is nothing that stops you from just enabling it.

config SPI_PL022
	tristate "ARM AMBA PL022 SSP controller"
	depends on ARM_AMBA

The "depends on" stops me.
