The PCIe controller register address in CCSR is different
on various platforms, the current code erroneously use
the hardcoded address (0xffe240000) and stride (0x10000)

MPC8548CDS. Also support of  i2c dm model.

i2c bugfixes for 2019.10
- misc: i2c_eeprom: verify that the chip is functional at probe()
- i2c: mxc_i2c: Remove i2c_idle_bus from probe
- i2c-mux-gpio: Fix GPIO request flag issue

Read a single byte from EEPROM to verify that it is actually there.

This is equivalent to Linux kernel commit 00f0ea70d2b8 ("eeprom: at24:
check if the chip is functional in probe()").

hs: fixed style check prefer kernel type 'u8' over 'uint8_t'

i2c_idle_bus is already used in i2c_init_transfer. So before each transfer
if the bus is not ready, the i2c_idle_bus will be used to force idle.
It is unnecessary to call it again in probe.

We found a issue when enabling i2c mux with the mxc_i2c. The mxc_i2c is probed
after mux probing. However, at this moment the mux is still in idle state not
select any port. So if we call i2c_idle_bus in probe, it will fail and cause
mxc_i2c probe failed.

When requesting GPIO, the GPIOD_IS_OUT is missed in flag, so the GPIO
is set the input mode not output and cause mux not work.
