[PATCH v2] PCI: rcar: Remove __clk_is_enabled() call

[marek.vasut@gmail.com]

From: Marek Vasut <marek.vasut+renesas@gmail.com>

Remove __clk_is_enabled() call, otherwise the following build error occurs:
  arm-linux-gnueabi-ld: drivers/pci/controller/pcie-rcar-host.o: in function `rcar_pcie_aarch32_abort_handler':
  pcie-rcar-host.c:(.text+0xdd0): undefined reference to `__clk_is_enabled'
This should be OK, since the bus clock are always enabled in probe() of the driver.

Fixes: a115b1bd3af0 ("PCI: rcar: Add L1 link state fix into data abort hook")

V2: Drop the __clk_is_enabled(), like it was done already in V1 of
    a115b1bd3af0 ("PCI: rcar: Add L1 link state fix into data abort hook")
