[12/89] clk: bcm: rpi: Remove pllb_arm_lookup global pointer

Commit Message

Maxime Ripard Feb. 24, 2020, 9:06 a.m. UTC

The pllb_arm_lookup pointer in the struct raspberrypi_clk is not used for
anything but to store the returned pointer to clkdev_hw_create, and is not
used anywhere else in the driver.

Let's remove that global pointer from the structure.
