ARM: lpc32xx: allow multiplatform build
All preparation work is done, so the platform can finally be moved into ARCH_MULTIPLATFORM. This requires a small change to the defconfig file to enable the platform. Link: https://lore.kernel.org/r/20190809144043.476786-14-arnd@arndb.de Signed-off-by: Arnd Bergmann <arnd@arndb.de>
