soc/tegra: cbb: Remove unnecessary print function dev_err()

platform_get_irq()<--platform_get_irq_optional() platform_get_irq_optional() return non-zero IRQ number on success, negative error number on failure, if IRQ number is 0, return -EINVAL. so the function platform_get_irq() never returns 0, and the print function dev_err() is redundant because platform_get_irq() already prints an error.

Eliminate the follow coccicheck warnings:
./drivers/soc/tegra/cbb/tegra-cbb.c:142:3-10: line 142 is redundant because platform_get_irq() already prints an error ./drivers/soc/tegra/cbb/tegra-cbb.c:152:2-9: line 152 is redundant because platform_get_irq() already prints an error
