[PATCH v1 04/10] misc: eeprom_93xx46: Hide legacy platform data in the driver

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

First of all, there is no user for the platform data in the kernel.
Second, it needs a lot of updates to follow the modern standards
of the kernel, including proper Device Tree bindings and device
property handling.

For now, just hide the legacy platform data in the driver's code.
