regmap: cache: Make sure to sync the last register in a block
regcache_sync_block_raw_flush() expects the address of the register after last register that needs to be synced as its parameter. But the last call to regcache_sync_block_raw_flush() in regcache_sync_block_raw() passes the address of the last register in the block. This effectively always skips over the last register in a block, even if it needs to be synced. In order to fix it increase the address by one register. The issue was introduced in commit 75a5f89 ("regmap: cache: Write consecutive registers in a single block write").
