uboot-sifiveu: drop PWM-related patches

These are dropped from later SDK releases, and don't compile
with the recent GCC14 updates as well.

-Subject: [PATCH 1/5] board: sifive: spl: Initialized the PWM setting in the
- SPL stage
-
-LEDs and multiple fans can be controlled by SPL. This patch ensures
-that all fans have been enabled in the SPL stage. In addition, the
-LED's color will be set to yellow.

-Set LED's color to purple in the U-boot stage. Because there are still

-The LED's color wil be changed from purple to blue before executing
