Add separate entry for Broadcom STB DPFE driver, selected by platforms
by default.  This allows further customization and compile testing.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

I have other changes around drivers/memory/Kconfig pending. Sending them
together would avoid conflicts.

The select is probably not warranted, see below.

Can you make it default ARCH_BRCMSTB and remove the select above?

With that:
