[PATCH v2] clk: imx: don't build i.MX/RTxxxx code for all users of CCF

[A. Sverdlin]

From: Alexander Sverdlin <alexander.sverdlin at siemens.com>

When commit 1d7993d1d0ef
("clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)")
introduced the parts of Linux Common Clock Framework, it was done for i.MX6
only and even had "depends on SPL_CLK_IMX6Q" conditions. Since commit
ccab06689aa2 ("clk: imx: expose CCF entry for all") the framework can be
re-used with SoCs of other vendors (say, TI), but NXP SoC-specific code is
still being build. Is is especially problematic for size-constrained SPL
images on TI AM62x.

Make the build of the i.MX/RTxxxx code not only dependent on
CONFIG_$(PHASE_)CLK_CCF, but also on CONFIG_MACH_IMX options which shall
cover the i.MX platform users.

This saves 2264 bytes on 32-bit ARM platforms [using CCF].
