ACPI: docs: enumeration: Drop ugly ifdeffery from the examples

Browse Source 
The ifdeffery around ACPI ID tables are ugly and in some cases
even less valuable than plain definitions. Drop them for good
to avoid spreading rather bad pattern.

Adding ACPI support for an existing driver should be pretty
straightforward. Here is the simplest example::
#ifdef CONFIG_ACPI
static const struct acpi_device_id mydrv_acpi_match[] = {
/* ACPI IDs here */
{ }
};
MODULE_DEVICE_TABLE(acpi, mydrv_acpi_match);
#endif
static struct platform_driver my_driver = {
...
.driver = {
.acpi_match_table = ACPI_PTR(mydrv_acpi_match),
.acpi_match_table = mydrv_acpi_match,
},
};

the platform device drivers. Below is an example where we add ACPI support
to at25 SPI eeprom driver (this is meant for the above ACPI snippet)::
