so that it supports the asymmetric LRCKs when the CKR[29:28]

If isoc split in transfer with no data (the length of DATA0
packet is zero), we can't simply return immediately. Because
the DATA0 can be the first transaction or the second transaction
for the isoc split in transaction. If the DATA0 packet with no
data is in the first transaction, we can return immediately.
But if the DATA0 packet with no data is in the second transaction
of isoc split in transaction sequence, we need to increase the
qtd->isoc_frame_index and giveback urb to device driver if needed,
otherwise, the MDATA packet will be lost.
A typical test case is that connect the dwc2 controller with an
usb hs Hub (GL852G-12), and plug an usb fs audio device (Plantronics
headset) into the downstream port of Hub. Then use the usb mic
to record, we can find noise when playback.
In the case, the isoc split in transaction sequence like this:
- SSPLIT IN transaction
- CSPLIT IN transaction
- MDATA packet (176 bytes)
- CSPLIT IN transaction
- DATA0 packet (0 byte)
This patch use both the length of DATA0 and qtd->isoc_split_offset
to check if the DATA0 is in the second transaction.

The commit 3bc04e28a0 ("usb: dwc2: host: Get aligned DMA in
a more supported way") rips out a lot of code to simply the
allocation of aligned DMA. However, it also introduces a new
issue when use isoc split in transfer.
In my test case, I connect the dwc2 controller with an usb hs
Hub (GL852G-12), and plug an usb fs audio device (Plantronics
headset) into the downstream port of Hub. Then use the usb mic
to record, we can find noise when playback.
It's because that the usb Hub uses an MDATA for the first
transaction and a DATA0 for the second transaction for the isoc
split in transaction. An typical isoc split in transaction sequence
like this:
- SSPLIT IN transaction
- CSPLIT IN transaction
- MDATA packet
- CSPLIT IN transaction
- DATA0 packet
The DMA address of MDATA (urb->dma) is always DWORD-aligned, but
the DMA address of DATA0 (urb->dma + qtd->isoc_split_offset) may
not be DWORD-aligned, it depends on the qtd->isoc_split_offset (the
length of MDATA). In my test case, the length of MDATA is usually
unaligned, this cause DATA0 packet transmission error.
This patch use kmem_cache to allocate aligned DMA buf for isoc
split in transaction. Note that according to usb 2.0 spec, the
maximum data payload size is 1023 bytes for each fs isoc ep,
and the maximum allowable interrupt data payload size is 64 bytes
or less for fs interrupt ep. So we set the size of object to be
1024 bytes in the kmem cache.

This patch depends on iram node and 'rockchip,force-iram' property.
the example on rk3399 to active this feature is as follows:
iram: sram@ff8d0000 {
compatible = "mmio-sram";
reg = <0x0 0xff8d0000 0x0 0x20000>; /* 128k */
};
&dmac_bus {
iram = <&iram>;
rockchip,force-iram;
};
if the 'rockchip,force-iram' not defined, fallthrough to normal usage.
