DMA move API tracking issue

[bugadani]

Basics

• #1716
• #1719
• #1856
• #1976

Peripheral support

• [x] SPI master
• [ ] SPI slave
• [x] I8080 #2191
  • #2268
• [x] Camera #2242
• [ ] AES
• [ ] PARL IO
• [ ] I2S
• [ ] Memcpy

Buffer features

• #2161
• [ ] Support other slice types besides u8.
• [ ] Support configuring burst mode
• [ ] Support configuring the "check descriptor ownership" feature on the DMA channel
• [ ] Support configuring the ownership write back feature in the DMA channel
• [ ] Allow users to create the Preparation struct (make it public)
• [ ] Expose an unsafe constructor for people to create buffers on the stack.
• [ ] Place the buffer view methods in internal ram since they're likely to be called in interrupts

Buffer types

• [ ] DmaTxStreamingBuf
• [ ] DmaTxCircularBuf
• [ ] DmaRxCircularBuf
• [ ] DmaReadOnlyBuf (for creating multiple bufs that point to the same buffer)
• [ ] Compressed buffer? Not sure if this should be in the hal

Note: This issue can be closed once the DescriptorChain struct is deleted.
