gpio: sx150x: move platform data into driver
The sx150x has some platform data definition in <linux/i2c/sx150x.h>
but this file is only included from the driver in the whole kernel
so move its contents into the driver.

| 23 | /** | ||
| 24 | * struct sx150x_platform_data - config data for SX150x driver | ||
| 25 | * @gpio_base: The index number of the first GPIO assigned to this | ||
| 26 | * GPIO expander. The expander will create a block of | ||
| 27 | * consecutively numbered gpios beginning at the given base, | ||
| 28 | * with the size of the block depending on the model of the | ||
| 29 | * expander chip. | ||
| 30 | * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO | ||
| 31 | * instead of as an oscillator, increasing the size of the | ||
| 32 | * GP(I)O pool created by this expander by one. The | ||
| 33 | * output-only GPO pin will be added at the end of the block. | ||
| 34 | * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor | ||
| 35 | * for each IO line in the expander. Setting the bit at | ||
| 36 | * position n will enable the pull-up for the IO at | ||
| 37 | * the corresponding offset. For chips with fewer than | ||
| 38 | * 16 IO pins, high-end bits are ignored. | ||
| 39 | * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down | ||
| 40 | * resistor for each IO line in the expander. Setting the | ||
| 41 | * bit at position n will enable the pull-down for the IO at | ||
| 42 | * the corresponding offset. For chips with fewer than | ||
| 43 | * 16 IO pins, high-end bits are ignored. | ||
| 44 | * @io_open_drain_ena: A bit-mask which enables-or disables open-drain | ||
| 45 | * operation for each IO line in the expander. Setting the | ||
| 46 | * bit at position n enables open-drain operation for | ||
| 47 | * the IO at the corresponding offset. Clearing the bit | ||
| 48 | * enables regular push-pull operation for that IO. | ||
| 49 | * For chips with fewer than 16 IO pins, high-end bits | ||
| 50 | * are ignored. | ||
| 51 | * @io_polarity: A bit-mask which enables polarity inversion for each IO line | ||
| 52 | * in the expander. Setting the bit at position n inverts | ||
| 53 | * the polarity of that IO line, while clearing it results | ||
| 54 | * in normal polarity. For chips with fewer than 16 IO pins, | ||
| 55 | * high-end bits are ignored. | ||
| 56 | * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line | ||
| 57 | * is connected, via which it reports interrupt events | ||
| 58 | * across all GPIO lines. This must be a real, | ||
| 59 | * pre-existing IRQ line. | ||
| 60 | * Setting this value < 0 disables the irq_chip functionality | ||
| 61 | * of the driver. | ||
| 62 | * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based | ||
| 63 | * IRQ lines will appear. Similarly to gpio_base, the expander | ||
| 64 | * will create a block of irqs beginning at this number. | ||
| 65 | * This value is ignored if irq_summary is < 0. | ||
| 66 | * @reset_during_probe: If set to true, the driver will trigger a full | ||
| 67 | * reset of the chip at the beginning of the probe | ||
| 68 | * in order to place it in a known state. | ||
