Cai Huoqing 9e28cfead2 net: mdio-ipq4019: Fix the error for an optional regs resource
The second resource is optional which is only provided on the chipset
IPQ5018. But the blamed commit ignores that and if the resource is
not there it just fails.

the resource is used like this,
	if (priv->eth_ldo_rdy) {
		val = readl(priv->eth_ldo_rdy);
		val |= BIT(0);
		writel(val, priv->eth_ldo_rdy);
		fsleep(IPQ_PHY_SET_DELAY_US);
	}

This patch reverts that to still allow the second resource to be optional
because other SoC have the some MDIO controller and doesn't need to
second resource.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
