docs: powerpc: vas-api: Fix the structure name and the ioctl number in the example

Browse Source 
struct vas_setup_attr does not exist; the name is struct
vas_tx_win_open_attr. The example also defines VAS_TX_WIN_OPEN with the
request number 1, while arch/powerpc/include/uapi/asm/vas-api.h has used
0x20 since the ioctl was added.

Use struct vas_tx_win_open_attr and 0x20.
