This resolves a deadlock scenario where ucsi_displayport_remove_partner holds con->mutex waiting for dp_altmode_work to complete while dp_altmode_work attempts to acquire it.

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 the platform driver's match table does not have to be extended.

And the call is made synchronous by polling DSTS continuosly for 20000 times in __dwc3_gadget_wakeup(). But it observed that sometimes the link is not active even after polling 20K times, leading to remote wakeup failures. Adding a small delay between each poll helps, but that won't guarantee resolution in future. Hence make the gadget_wakeup completely asynchronous. Since multiple interfaces can issue a function wakeup at once, add a new variable wakeup_pending_funcs which will indicate the functions that has issued func_wakup, this is represented in a bitmap format. If the link is in U3, dwc3_gadget_func_wakeup() will set the bit corresponding to interface_id and bail out. Once link comes back to U0, linksts_change irq is triggered, where the function wakeup command is sent based on bitmap.
