Subject: [PATCH 06/10] serial: altera_jtaguart: switch status to u32

'status' is assigned a result from readl(). There is no need for the
variable to be 'unsigned long'. readl() returns 32bit values.

Provided, this is a Nios II driver (32-bit), there is no change in
semantics. This only makes the type explicit.
