[PATCH 1/8] clk: stm32f4: allow building under COMPILE_TEST and fix the build

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: Ahmad Fatoum <a.fatoum@barebox.org>

No in-tree defconfig combines ARCH_STM32 with this driver, so it has
never been compiled and doesn't build:

  clk-stm32f4.c:1665:20: error: 'struct clk_mux' has no member named 'width'

barebox' struct clk_mux carries a mask like Linux', so assign it
verbatim as upstream does; the tables already hold unshifted masks.

The symbol can't be enabled at all either: its prompt is gated on
COMPILE_TEST and it has no default, and the only in-tree selector of
ARCH_STM32 is ARCH_STM32MP, which uses clk-stm32mp1.c instead.

As I still hope to finish upstreaming my STM32F support one day, let's
just ensure the driver compile tests for now.

Fixes: 27923adcd1b7 ("clk: add clock driver for stm32f4 and stm32f7")
