This patch try to fix this issue by caching the dma-buf attachments and
stores the cache list to dtor_data of dma-buf structor. The dma-buf
attach with cache will try to find cached attachment first and return
the valid instance.
This patch also store the deattch operation to dtor of dma-buf structor
by dma_buf_set_destructor.

dma-buf destructor support is useful as it allows clients an opportunity
to undo any attributes, such as security attributes, they have applied to
the dma-buf's memory.
The destructor is called when the dma-buf is freed, if the destructor
returns an error the dma-buf's exporter release function is not called in
order to ensure that memory which has not been properly cleaned up isn't
returned to the system.

This patch aims to configure usb for better compatibility.
1. Set ssc downward spread spectrum.
2. Enable the adaptive Continuous Time Linear Equalizer (CTLE).
3. Set ssc to 31.5KHz for 24MHz ref clk.
4. Adjusts the PLL the parameters for USB Rx to pass the
Receiver Jitter Tolerance Test, and it's helpful to
improve the USB 3.0 signal compatibility.

ZONE_DMA32 is enabled by default on android12-5.10, yet it is not
needed for all devices, nor is it desirable to have if not needed. For
instance, if a partner in GKI 1.0 did not use ZONE_DMA32, memory can
be lower for ZONE_NORMAL relative to older targets, such that memory
would run out more quickly in ZONE_NORMAL leading kswapd to be invoked
unnecessarily.
Correspondingly, provide a means of making ZONE_DMA32 empty via the
kernel command line when it is compiled in via CONFIG_ZONE_DMA32.

For RK3588 EVB design, the USB vbus is always pull-up, and the USB
controller can not detect that the device was unattached. So based on
the orientation switch process, control the bvalid status via writing
U2PHY GRF when the Type-C controller detected that the device was
attached or unattached.
