[PATCH 2/2] PCI: rcar-gen4: Inline rcar_gen4_pcie_host_perst_assert() again

[Marek Vasut <marek.vasut+renesas@mailbox.org>]

The rcar_gen4_pcie_host_perst_assert() no longer has any purpose,
inline reset_control_assert()/reset_control_deassert() back into
the rest of the code and drop rcar_gen4_pcie_host_perst_assert().
