[U-Boot] [PATCH 031/080] serial: ns16550: Fix address translation

[Mario Six]

The dev_read_addr function does not do any bus translations, and just
returns the raw address read from the device tree, which makes the
driver not work on systems that need bus translations to get the actual
memory address of the device's register space.

Since the dev_read_addr function is widely used, we refrain from
modifying it, and instead read the raw address from the device tree, and
apply the bus translations using the recently introduced
dev_translate_address function.
