i3c: mipi-i3c-hci: Round IBI data chunk size to HW supported value

Browse source

The dma.c: hci_dma_init() sets the CHUNK_SIZE field in the IBI_SETUP
register incorrectly if the calculated ibi_chunk_sz is not exactly
2^(n+2) bytes, where n is 0..6.

Fix this by rounding the chunk size up to nearest 2^(n+2) bytes.
