[U-Boot] [PATCH v5 05/18] clk: Extend struct clk to provide clock type agnostic flags

[Lukasz Majewski]

This commit extends the struct clk to provide information regarding the
flags related to this devices.

Those flags are clk device agnostic and indicate generic features
(like e.g. CLK_GET_RATE_NOCACHE - the need to always recalculate the rate).
