[PULL v2 19/32] hw/riscv: sifive_u: Simplify the GEM IRQ connect code a little bit

[Alistair Francis]

From: Bin Meng <bin.meng@windriver.com>

There is no need to retrieve all PLIC IRQ information in order to
just connect the GEM IRQ. Use qdev_get_gpio_in() directly like
what is done for other peripherals.
