Subject: [PATCH 2/3] clk: Merge prepare and unprepare sections

<linux/clk.h> contains two consecutive #ifdef/#else/#endif sections
that check for CONFIG_HAVE_CLK_PREPARE: one for prepare-related
functionality, and a second for unprepare-related functionality.
Reduce #ifdef clutter by merging them.
