[PATCH] pata_pdc2027x: Remove unnecessary error check and coding style error.

[Arvind Yadav]

Here, The function pdc_hardware_init always return zero. So it is not
necessary to check its return value.

Fix these checkpatch.pl error:

ERROR: space prohibited after that '~' (ctx:WxW)
+		mask &= ~ (1 << (6 + ATA_SHIFT_UDMA));

ERROR: spaces required around that '?' (ctx:VxW)
+	long pout_required = board_idx? PDC_133_MHZ:PDC_100_MHZ;

ERROR: that open brace { should be on the previous line
+	const struct ata_port_info *ppi[] =
+		{ &pdc2027x_port_info[board_idx], NULL };
