From: Marek Vasut <marek.vasut+renesas@xxxxxxxxx>
Replace __clk_is_enabled() with pm_runtime_suspended(),
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'
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")
V3: Use pm_runtime_suspended() instead of __clk_is_enabled()
