Reduce the SPL binary size by building some clocks only for the non-SPL case, such as Ethernet and PWM and by also building ECSPI and QSPI when their respective drivers are enabled.
On a imx8mm_evk_defconfig the following SPL binary reduction was observed.
Prior to this series:
$ aarch64-linux-gnu-readelf -s spl/u-boot-spl | sort -nk 3 | grep imx8mm_clk_probe 766: 00000000007f34c8 4100 FUNC LOCAL DEFAULT 1 imx8mm_clk_probe
After this series:
$ aarch64-linux-gnu-readelf -s spl/u-boot-spl | sort -nk 3 | grep imx8mm_clk_probe 766: 00000000007f34c8 3316 FUNC LOCAL DEFAULT 1 imx8mm_clk_probe
Total reduction: 4100 - 3316 = 784 bytes.

I'm not really convinced of those two. I mean with should maybe think about some different approach of clock framework to reduce the size
