fix(otg_v2): correct UEP_DMA bit_size from 16 to 32

[Dummyc0m]

Fix applied according to the datasheet.

Could you provide the source of the change? According to the RM doc:

😮‍💨 Sigh.... WCH documentation is inconsistent at best...

This is from CH32FV2x_3xRM.pdf

The address map also agrees with this, each of the DMA register are spaced 4 apart:

Logically it also makes sense, since we are expected to fill a memory address into there, which would be 32 bits.

The register name on my manual seems to be R32 indicating it is a 32bit register.

@andelf if you get a chance to take a look at this would be extremely helpful :)

Thanks! I'll check the EVT source code for these registers.

perfect. We checked they seems to cast to uint32_t as well but feel free to double check

Let's get this merged.
