Masahiro Yamada ca2d13ec6e mmc: sdhci-of-at91: make MMC_SDHCI_OF_AT91 depend on HAVE_CLK
If sdhci-of-at91.c is compiled without CONFIG_HAVE_CLK, the line

  caps1 |= FIELD_PREP(SDHCI_CLOCK_MUL_MASK, clk_mul);

... emits "FIELD_PREP: value too large for the field" warning.

The compiler seems to decide clk_mul is constant (unsigned int)-1,
because clk_get_rate() returns 0 when CONFIG_HAVE_CLK is disabled.

Add HAVE_CLK to the depenency since this driver does not work without
the clock APIs anyway.
