Subject: [PATCH v3 09/11] PCI: imx: Consolidate redundant if-checks

Consolidated redundant if-checks pertaining to imx_pcie->phy. Instead of
two separate checks, merged them into one to improve code readability.

if (imx_pcie->phy) {
	... code 1
}

if (imx_pcie->phy) {
	... code 2
}

Merge into one if block.

if (imx_pcie->phy) {
	... code 1
	... code 2
}
