The **rdev of 'struct bcm590xx_reg' isn't used anywhere in the driver so
remove it.

BCM590XX_NUM_REGS is known in compile time.
Use array to save desc and *info makes the code simpler.

Well, ok. It was coded for dynamic allocation because I'm starting to
work on BCM59054 support, which is similar but different. The actual
regulators are different but, due to luck, the total number is the
same between 59056 and 59054...so this can still work for the moment.
However, another 590xx part does have a different number of regulators
so I'm not sure this is worth doing when we know we'll go back to
dynamic allocation in the future.

Then it' ok to keep the code as is, just drop this patch.
