mwifiex: rebase some patches

[kitakar5525]

Hi, I slightly cleaned up mwifiex patches.

1. revert some existing patches to improve changes and commit messages
2. added improved patches

mwifiex: pcie: disable bridge_d3 for Surface gen4+ Changes from the previous patch:

• Use recently added quirk implementation and apply for only Surface gen4+ devices
• Moved to the bottom of probe() so that quirk implementation can init before use

mwifiex: add allow_ps_mode module parameter Changes from the previous patch:

• Use -EPERM instead of -1 for return value when enabling ps_mode is disallowed by modparam
• changed allow_ps_mode modparam permission from 0444 to 0644 because it can be changed after probe as well
• Simplified comment in code
• Simplified print message

mwifiex: mwifiex: print message when changing ps_mode Changes from the previous patch:

• Simplified print messages

mwifiex: disable ps_mode explicitly by default instead Changes from previous patch:

• Squashed mwifiex: sta_cmd: add comment for not enabling ps_mode by default and mwifiex: sta_cmd: do not enable ps_mode by default
• Disable ps_mode explicitly instead of just removing the code

Removing the code that enables ps_mode might be enough, but there's also no reason not to explicitly disable it. So, let's disable it explicitly.

I feel that we don't need the patch mwifiex: pcie: disable bridge_d3 for Surface gen4+ anymore. When I tried on Arch's v5.8 kernel, it survived several suspend. And the bridge_d3 was already set to false. But I'm not so sure. For now, let's keep the patch and investigate it later.

Interesting. You could try to add a sysfs file to override the quirks from user-space. That should allow us to test if different things are still needed without having to re-compile things, at least if they're implemented as quirks.
