clk: analogbits: Fix incorrect calculation of vco rate delta
[ Upstream commit d7f12857f095ef38523399d47e68787b357232f6 ] In wrpll_configure_for_rate() we try to determine the best PLL configuration for a target rate. However, in the loop where we try values of R, we should compare the derived `vco` with `target_vco_rate`. However, we were in fact comparing it with `target_rate`, which is actually after Q shift. This is incorrect, and sometimes can result in suboptimal clock rates. Fix it.
