spi: spi-mpc52xx-psc: Fix an unsigned comparison that can never be negative

Browse Source 
In struct mpc52xx_psc_spi, the variable 'irq' is declared as an unsigned int.
The comparison of variable 'irq'  with signed int operand is incorrect. Also,
the return value from the call to platform_get_irq(pdev,0) is int and it is
assigned to an unsigned int variable 'irq', thus redeclaring the type of
variable 'irq' to signed int.

This fixes warning such as:
drivers/spi/spi-mpc52xx-psc.c:332:5-13:
WARNING: Unsigned expression compared with zero: mps -> irq < 0
