Subject: [RFT][PATCH] regulator: bcm590xx: Fix .enable_reg for BCM590XX_REG_VSR

Current implementation missed the case BCM590XX_REG_VSR, so
bcm590xx_get_enable_register() returns 0 when id is BCM590XX_REG_VSR.

Hi Matt,
Current code looks strange becasue bcm590xx_get_enable_register() returns 0
for BCM590XX_REG_VSR but there is a BCM590XX_VSRPMCTRL1 defined in the code.
I don't have the h/w, and I even cannot find the datasheet on the internet.
I might be wrong, but just in case this might fix a real bug.
Please help to review and test this patch.

Thanks,
Axel
