net: wwan: t7xx: Ensure init is completed before system sleep
When the system attempts to sleep while mtk_t7xx is not ready, the driver
cannot put the device to sleep:
[ 12.472918] mtk_t7xx 0000:57:00.0: [PM] Exiting suspend, modem in invalid state
[ 12.472936] mtk_t7xx 0000:57:00.0: PM: pci_pm_suspend(): t7xx_pci_pm_suspend+0x0/0x20 [mtk_t7xx] returns -14
[ 12.473678] mtk_t7xx 0000:57:00.0: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x1b0 returns -14
[ 12.473711] mtk_t7xx 0000:57:00.0: PM: failed to suspend async: error -14
[ 12.764776] PM: Some devices failed to suspend, or early wake event detected
Mediatek confirmed the device can take a rather long time to complete
its initialization, so wait for up to 20 seconds until init is done.
