rtwo: replace debug blink instrumentation with a boot progress bar
Confirmed on hardware that the chainload boots. The per-call blink instrumentation lived in hot paths (clk_enable/qcom_gate_clk_en/serial probe) and did a full 10 MiB framebuffer clear + cache flush on every call, noticeably slowing boot. Replaced with a single progress bar hooked once per INITCALL step (include/initcall.h) plus an explicit 100% draw at the end of board_late_init(), touching only the bar's rectangle instead of the whole screen. Kept the real fixes from the same patch (qcom,kalama-gcc-v2 GCC compatible, the IS_ERR(clk) handling in serial_msm_geni.c) untouched.
