The Cypress HX3 USB3.0 hubs use different PID values depending on the product variant. The comment in compatibles table is misleading, as the currently used PIDs (0x6504 and 0x6506 for USB 3.0 and USB 2.0, respectively) are defaults for the CYUSB331x, while CYUSB330x and CYUSB332x variants use different values. Based on the datasheet [1], update the compatible usb devices table to handle different types of the hub. The change also includes vendor mode PIDs, which are used by the hub in I2C Master boot mode, if connected EEPROM contains invalid signature or is blank. This allows to correctly boot the hub even if the EEPROM will have broken content. Number of vcc supplies and timing requirements are the same for all HX variants, so reuse existing onboard_hub_pdata.

Currently, the onboard Cypress CYUSB3304 USB hub is not defined in the device tree, and hub reset pin is provided as vcc5v0_host regulator to usb phy. This causes instability issues, as a result of improper reset duration.

The fixed regulator device requests the GPIO during probe in its inactive state (except if regulator-boot-on property is set, in which case it is requested in the active state). Considering gpio is GPIO_ACTIVE_LOW for Puma, it means it’s driving it high. Then the regulator gets enabled (because regulator-always-on property), which drives it to its active state, meaning driving it low.

The Cypress CYUSB3304 USB hub actually requires the reset to be asserted for at least 5 ms, which we cannot guarantee right now since there's no delay in the current config, meaning the hub may sometimes work or not. We could add delay as offered by fixed-regulator but let's rather fix this by using the proper way to model onboard USB hubs.

Define hub_2_0 and hub_3_0 nodes, as the onboard Cypress hub consist of two 'logical' hubs, for USB2.0 and USB3.0. Use the 'reset-gpios' property of hub to assign reset pin instead of using regulator. Rename the vcc5v0_host regulator to cy3304_reset to be more meaningful. The vdd-supply and vdd2-supply properties in hub nodes were skipped, because hub power supplies are always enabled based on HW design.
