mfd: 88pm800: Fix I2C device resource leak if probe fails
During probe the driver allocates two dummy I2C devices for subchips in
function pm800_pages_init(). Additionally this function allocates
regmaps for these subchips. If any of these steps fail then these dummy
I2C devices are not freed and resources leak.
On pm800_pages_init() fail the driver must call pm800_pages_exit() to
unregister dummy I2C devices.
