[U-Boot] [PATCH] video, ipu: make ldb_clock configurable

make the ldb_clock configurable through the new define CONFIG_SYS_LDB_CLOCK. This is needed as the ldb clock is not always 650000000, for example on the aristainetos2 board, where the ldb clock derives from PLL5 clock.

You might want to count the zeros here:
+#define CONFIG_SYS_LDB_CLOCK 650000000
That big a number will break existing code.
+#endif
static struct clk ldb_clk = { .name = "ldb_clk",
- .rate = 65000000,
- .rate = CONFIG_SYS_LDB_CLOCK, .usecount = 0,
};
