memory: brcmstb_dpfe: add separate entry for compile test

Add separate entry for Broadcom STB DPFE driver, enabled by default on
ARCH_BRCMSTB.  This allows compile testing.

+         This driver provides access to the DPFE interface of Broadcom
+         STB SoCs. The firmware running on the DCPU inside the DDR PHY can
+         provide current information about the system's RAM, for instance
+         the DRAM refresh rate. This can be used as an indirect indicator
+         for the DRAM's temperature. Slower refresh rate means cooler RAM,
+         higher refresh rate means hotter RAM.
