The Elan ekth6a12nay touch screen chip same as Elan eKTH6915 controller
has a reset gpio. The difference is that they have different
post_power_delay_ms.

Changes between V3 and V2:
- 1. "ekth6915" isn't a fallback, modify it.
v2: https://lore.kernel.org/all/20240715073159.25064-2-lvzhaoxiong@huaqin.corp-partner.google.com/
Changes between V2 and V1:
- 1. Respin the series on top of v6.10.

Elan-ekth6a12nay requires reset to pull down time greater than 10ms,
so the configuration post_power_delay_ms is 10, and the chipset
initial time is required to be greater than 300ms,
so the post_gpio_reset_on_delay_ms is set to 300.
